Debian :: Sometimes Boot Wait On Random - Nonblocking Pool Is Initialized
Dec 4, 2015
Sometime system wait during boot a long time on
Code: Select allrandom: nonblocking pool is initialized and Code: Select allPM: Starting manual resume from disk etc.
When everything is ok boot took around 20seconds. But when this problem occur it can take around 5 minutes. It occure during normal boot, but there are some information about resume from hibernation in log. But I didn't hibernate it. And hibernation doesn't work reliably so I removed uswsusp because I tried to fix hibernation with installing uswsusp first.
My laptop: MSI EX600X-033Sk (C2D T5250, Nvidia 8400g, It has firewire, usb2.0, ...)
I tried to google stuff like "Jessie slow boot", "Stack on random: nonblocking pool is initialized" etc but I didn't found any solution.
Here is few parts of my kern.log:

I installed ubuntu 10.10 on a machine that had windows 7 x64. itts installed on a seperate HD, but now when I boot to the harddrive with windows 7 all i get is "verifying DMI pool data" how do I fix this so I can get back to windows 7 as well?
I created my data pool using /dev/disk/by-id and things went well. a recent view of zpool status however showed /dev/sdb and /dev/sdc being used instead. how can I be sure a rearrangement of my disks wont cause error?
I had Fedora11 (default layout) running on a separate hard drive (winXP on the other drive). After the FC drive failure I replaced the drive and did a fresh install again. This time I tried a custom layout to keep the /home on a separate partition. The installation went without a hitch, but on first boot the system hangs with "Verifying DMI Pool Data......"
XP boots fine though. Looks like grub doesn't get loaded. I can boot with the installation cd and get into recovery mode, everything seems fine on the fedora disk. Fdisk result:
I'm running home server on Debian stable with DHCP, DNS, Mail, VDR, Filesharing and my Weatherstation as main services. The filesharing is used to mount homes at clients. The machine features an Athlon BE-2300, 3GB RAM, GB-LAN, 1TB and 1.5TB SATA HDD plus HDDs for backups. Mainboard has an NVIDIA chipset with
Code: nVidia Corporation MCP65 SATA Controller (rev a3) The primary disks are running in RAID1 + LVM.
1 is the first partition so windows finds it nicely. Before install, i unplugged my hdds so that grub wouldn't get confused. I told the installer to put the full install on sda3 with no swap space. I checked (advanced button on summary page) that bootloader is being installed to the usb on dev/sda (sda since no other drives attached). This should put it in the MBR (i think?)
Seems like I pressed all the right buttons huh? Is there a way to diagnose grub and see what's wrong? is there a reason grub may not initialize properly from a usb drive?
I've run into a situation where when performing a pxe/preseed install the system boots up into the install without issue, getting a dhcp address, then the installer begins to configure the network and it gets to where it request a dhcp address and it instantly fails the install stating that we are either not using dhcp or it's slow.
I've added d-i netcfg/dhcp_timeout string 600 to the preseed file but it doesn't seem to be honoured here since it doesn't wait 600 seconds before failing. I have 2 other identical systems that install using the same preseed file but the installer completes as expected. This system has no issues installing centos just debian fails. I did try, once the install failed, to switch to the console and run udhcpc and the server received the address reserved for it.
Is there a method to force debian installer to wait a bit longer for the dhcp server besides what I've already done?
I seem to be having a problem booting into ubuntu 10.04 (and 9.10 before I upgraded a while back). It's been ongoing for a while now, but I can't seem to actually even get to the login screen. Some kernels just give me a blank screen, and others hang at the ubuntu logo (http://i.cbsi.com.au/story_media/339...ic-koala_1.jpg). It seems to be totally random, and I can't seem to even narrow down which kernels do what. It seems to be a game every time I reboot. Perhaps it has something to do with the beta 2.6.32-rc6 kernel I installed (by clicking on the .deb) a while back? I'm not too sure how to uninstall it, but I first installed it I think back at 9.04, and it always seems to be the first option in grub. Can I clean out my old kernels somehow? Or is that dangerous?
Maybe it's caused by graphics drivers? "Safe mode" doesn't seem to work any better though. And I can't get to the TTY terminals by <ctrl><alt><1-6> either, which would suggest to me that it isn't a graphics issue? I don't see the login screen, nor do I always see the splash screen.
I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.
I have triple boot pc (xp, ubuntu, and fedora), installed in that order. xp and ubuntu seem to be stable. i have had to pull the power cord 3 or 4 times while booted in fedora. i noticed the last 2 times i can still move the mouse around, but can't get it to open anything. the keyboard is locked up, can't alt-f1 or f2 or anything to get console. can't get it to do anything, other than watch the mouse tail move around (weird).
i installed a new power supply (and at least i now have a power switch - the old one never had one), but that didn't fix the lock up problem. i haven't ran yum update since the fc10 live cd gnome install. was planning on doing that later.. not sure how long it will stay up to download all the 300 or so updates. right now the only thing open is a terminal (can't type in it).. what should i look at to fix this lock up problem?
I'm having trouble with Ubuntu 11.04. Every now and then when my laptop boots into the OS (It's a Toshiba Satellite L10) I get a weird desktop layout, that I have never used before (it has happened a few times though).
I recently removed windows 7 from my computer and am now only using ubuntu. I used a live cd to grow the partition to use the new available space, but now the system just hangs at the Verifying DMI pool data section of bios. This is usually the first thing before grub loads.
I was a windows XP user and one fine day my windows crashed and blue screen of death appeared. I have downloaded Ubuntu and created an ISO image on my pendrive with the help of the another computer as per the steps mentioned on the linux website. Now when am tryin to boot my corrupt PC with pendrive i cannot move beyond the comment " verifying DMI pool data" nothing happens later.
After upgrade to 10.04, my disks are randomly named (sda, sdb, sdc) at each boot. My drive labeled "XP" is sometimes named "sdb" and sometimes "sdc", while my other drive "DATA" is respectively "sdc" or "sdb". This wasn't the case before upgrade with KUbuntu 9.10.
Due to this random naming, my auto-mount in fstab often fail at boot time !
Any solution for this (not found here by myself) ?
Is this linked to Grub troubles reported many times here ?
Not having a good night. Typing away on some code and load & run my latest changes in chrome, mouse starts lagging and system slows right down, ok maybe it's a bug in chromeI close chrome, try to get to a terminal to kill processes, no luck, go away for a while and come back hoping it sorts itself out, still frozen so I reboot.Now I get a horrible crash almost immediately on boot with a bunch of cryptic numeric error codes then:
Begin: Running /scripts/local-bottom ... mounting /dev on /root/dev failed: no such file or directory
I have a Raid0 setup (see below for details) connected to the ICH10R raid chip on my Gigabyte EX58-UD4P motherboard. On every second og third boot I get the following error:
Code: udevd-work[157]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory udevd-work[179]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory The system halts for a seconds or two and then boots on like nothing has happend.
My setup is as follows:
Two 500gb discs in Raid0 on the ICH10R. The first partition 100 mb is a Windows 7 system partition (gaming etc.) and then a 300gb partition for the actual Windos install. Then Ubuntu 10.10 with /, /home, /swap and then five data partitions. Grub is on the Windows system partition.
Ubuntu 10.10 x64 installed via USB. No problems during install. Besides that I have 2x300gb dics on the Gigabyte built in raid controller. Installed with a Hackintos setup using Mac software raid.My fstab looks like this:
Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5).
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
I have an IBM server with a: "SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)", meaning kernel module CONFIG_FUSION. This is the real hardware, not emulated by vmware. With recent kernels (2.6.30-35) the boot results in one of three situations:
1.) Most common: kernel panic, way too long stack dump to see anything useful but did have a terminal briefly to debug this and its just not being able to communicate with the scsi subsystems, google for errors found nothing of use.
2.) Sometimes: A hang waiting for the scsi disks after the controller fails to initialize properly, does not pass in a couple of hours.
3.) Very rarely: A long wait for the scsi controller to initialize but a succesful boot afterwards. ACPI subsystems are taking all CPU power. This is the state the machine is at now, working somewhat.
I can boot the machine with a Gentoo live install disk (kernel 2.6.29 I think) and under that version the controller initializes instantly and there are no problems whatsover using the disks so the hardware seems to be solid!
There were some MPT changes in 2.6.25rc5 so thats the latest kernel I've tried. The errors during boot change to a bit more verbose but thats about it. Unfortunately I don't have a serial terminal with me anymore so cannot capture these errors but it was something about an "unexpected doorbell" with 2.6.24 and nothing memorable with .25. Long story short tho, googling the errors provides no solutions and the little I find points to the controller being too slow to initialize somehow.
I'm running out of ideas here and the server is burning fans like theres no tomorrow (ACPI taking everything it can) so is my only option to downgrade to 2.6.29 (and downgrade udev, lvm2, so on and on and on)? I can't believe I'm the only one for whom this has been broken for several minor versions.
Kernels tried:
- 2.6.29-gentoo (live disk) - works, blazing fast initialization - 2.6.32-gentoo-r7 - random boot failures and successes - 2.6.34-gentoo-r1 - same - 2.6.35-rc5 vanilla - same, better errors, zero useful google results.
I'm not very keen on longshot attempts since it can take a couple of hours of panic-loops to get the machine booted up again and the server functions cannot be transferred to another machine. Also, I'm a bit hesitant to mention this, but the boot has only ever succeeded when a serial cable with something at the other end is connected. At first it was the testing serial terminal and now its just a connection to a UPS.
Attached: bootlog of succesfull-ish boot with 2.6.34 (had to cut some out to make the sizelimit):

I have a question regarding OpenVPN. I have configured my own vpn server. It is in a private network 192.168.0.0. The ip addresses I am using for the vpn connection are in the 10.9.1.0 network but I want to connect my ovpn clinets to the 192.168.0.0 network. I read the manuals and I think the "push route" command will work for me, but I cannot understand fully the description of the command "push route".
# Push routes to the client to allow it to reach other private subnets behind the server. # Remember that these private subnets will also need to know to route the OpenVPN client # Address pool (10.8.0.0/255.255.255.0) back to the OpenVPN server. ;push "route 192.168.10.0 255.255.255.0" ;push "route 192.168.20.0 255.255.255.0"
So the questions: 1. These private subnets behind the server are routed from my vpn server or from another router 2. How these private subnets "know to route" the open vpn address pool, is this a configuration of the router for this networks (192.168.0.0)or ?
Why is it that about 98 to 99% of the time my computer will boot to Ubuntu/Lucid just fine but on rare / random occasions after seeing the initial BIOS boot screen and initial cursor just after initial BIOS boot screens, the video will just go BLANK, i.e. does not boot to Ubuntu desktop ?
If I then do ALT,CRL,DEL sequence the SPLASH screen is displayed on the monitor and the system then reboots and then goes thru the complete boot process all the way to the desktop just fine.Why this occasional failure to boot completely to the desktop ?
How to use git? I want to download git: [URL]. All what I get is: ~$ git clone [URL] Initialized empty Git repository in /home/john/xfce4-generic-slider/.git/ fatal: [URL] not found: did you run git update-server-info on the server?
I have a slight problem with an applet I'm trying to run. I don't have problems running any other java applets from other websites or anything but for some reason the applet I developed shows the gray-screen and says 'Start: applet not initialized.' at the bottom.
There are no errors in the error console.Java is working on my web browser (mozilla firefox).I'm running Ubuntu 10.10.Here's my code, the program is for my friend and she uses a mac, so is this issue specific for Ubuntu? I made the applet using Eclipse Ganymede.
I got this working before, but now I have a freshly installed Ubuntu 10.04 and I wanna play yahoo pool and I followed all those crazy insane commands they posted but they (java) didn't help at all, their support and help is really poor as I get errors like directory does not exist or no such file. I basically installed the jre-6u21-linux-i586.bin file in my home directory like and used all their commands like cd /home and all that. Here is my ls output they say always to check, but it seems like I installed it but I can't get it installed with firefox together.

System is Wheezy 7.9 with lightdm and MATE desktop.
I have 128GB SSD with various partitions for operating systems and a separate HDD for the /home folders for each OS. Wheezy is my primary system, the others, apart from the original XP are experimental.
/etc/lightdm/lightdm-gtk-greeter.conf is Code: Select all# # background = Background file to use, either an image path or a color (e.g. #772953) # show-language-selector (true or false) # theme-name = GTK+ theme to use
[code]....
The problem is that each time I use the Ubuntu system and I change back to Debian, the greeter background contains snippets of whatever was displayed while I was in Ubuntu. What I don't understand is how this can happen, given that the operating systems are installed in separate partitions with separate /home partitions as well. After I have used Debian and restart, the greeter screen is clear, as it should be.URL....
I try to open an application, and it's painfully slow, and i think "this is weird i've had it open just 10 seconds ago and it should be in the cache". the disk is constantly working, so maybe i ran out of ram and it's swapping, so i check: according to 'free -m', about 200m of 2g ram is used (without buffers/cache), but still also 200m of swap is used, although swappiness is set to 1 (low tendency to swap). so this is not normal.also, kswapd0 is eating pretty much cpu (but not 100%). switching to tty1, logging in, and starting iotop takes about a minute. according to iotop, about 8 random processes (could be a browser, could be some daemon) have 99% IO activity (i'm not sure what that means, how can 8 processes take 99% each?).after the first 3 times, i disabled swap by adding swapoff -a to rc.local, but it's still the same, and kswapd is still among the cpu-eaters.
My new laptop has an Intel i7 processor and 6gb DDR3 of ram, I really didn't know which architecture to use and I ended up installing Debian amd64 ( Squeeze because it's the one I used in my older computer ). I decided to add Backtrack 4 R2 repositories to my /etc/apt/sources.list, and after doing:
#aptitude update
I found out that they don't have support for amd64 repos...1st: is it possible to make my aptitude accept the Backtrack's i386 repos? if yes, how? if not, can I switch to i386 and be able my laptop's 6gb ram ? if yes, would that sacrifice a lot of performance?( I did choose amd64 because I thought that I wouldn't be able to use more than 4gb of ram with the i386 build. Is this correct? )
Final note: I want you to know that I already tried to install aircrack from Debian's repos but it's not present, I'm not sure if there's something wrong with my configuration.
*this is what my /etc/apt/sources.list looks like:

I have installed Debian Wheezy on my laptop today, which went relativly smoothly. The only problem that is left (for now) is that my wireless LAN disconnects 1-2 times every 30 minutes, just to reconnect a few seconds later. Obviously that is very annoying, especially when watching streams on twitch, videos on youtube and so on.A thread I found on google suggested to use the command dmesg right after my wireless lan connection drops. So I waited for the next disconnect, issued the command and got the following output:
Code: Select allwlan0: deauthenticated from 00:1f:3f:d4:25:6a (Reason: 14) wlan0: deauthenticating from 00:1f:3f:d4:25:6a by local choice (reason=14)
I wondered what that reason code meant and found this website, which states that the code 14 stands for: Message integrity code (MIC) failure
