Slackware :: Frequent Unexpected (and Not Logged) Reboots
Mar 22, 2010
I'm running a gateway - router pc with slack13 32bit on a pIII PC. I am using huge.s kernel. Apart from a firewall script, I have installed ulog deamon. I am also using the pc as a transparent proxy, a dns cache and a vpn server. So I haven't installed weird stuff. I have not installed X or any desktop environment. I get unexpected reboots however, and /var/log/messages does not state anything, not dmesg does. I am thinking of running a disk test on each disk ( one OS disk and one disk for the squid cache) and a memory test. I am not sure its a hardware issue (like the PSU, disk or RAM) because I used to let this pc ON for several weeks even before I started configuring it... and I couldn't hear anything wrong. Now I get to hear disks spinning down and up again, and even that very first boot sound you hear when you switch on the PC.

I'm having, oddly enough, stability problems on my main slackware desktop. Whenever I try to do certain things, for instance going fullscreen on a flash video, starting regnum online or open arena, it drops out of X into the command line with a few error messages (next time it crashes I'll post the messages). On occasion, it'll do that without any input. Now, there's a few major changes I've had on the desktop since yesterday, chiefly that I've been able to connect it to the net for the first time in a few months. Now because of this, I've been installing plenty of software from slackbuilds, plus flash from adobe (necessary evil). I'm using xfce with some compositing on a geforce Ti 4200 AGP 8x 64Mb with nvidia drivers installed and dual monitors, each now set to 1280x1024 and in twinview, pentium 4 2.8Ghz, 1 GB ram. HDD has a 70GB ext3 slack partition, triple booting with 80GB ext4 ubuntu lucid partition and 40GB ext4 mint isadora.

Can't boot the x64 version of the official install DVD or any mini-image from Alien Bob. Either way, the computer reboots a few seconds after loading the kernel. Running 13.1 x64 on the very same hardware right now. Edit: this system ran Slack 100% stably for about a year, and Ubuntu for a few years before that. I am using it to write this, and have no reason to suspect any kind of hardware failure. memtest passes.
I managed to snap a picture of the screen just before the reboot, here is the end:
Code:
Just as reported by AlleyTrotter below, every installation media I tried for 13.1 hangs right after loading initrd, and every installation media I tried for 13.37 rebooted with the message posted just above. I havent tried all the combinations (official, alien, DVD, CD, x64, x32, USB, PXE), but I tried a lot of them, all with the same consistent results.
I have 4G of RAM, and the workaround provided below by AlleyTrotter (booting with huge.s mem=3700M) worked. That is to say, I booted from the official x64 DVD and was able to log in as root, and everything seemed OK. I did not try to install, though, since I already successfully installed a minimal system from 13.0 media and then upgraded directly to full 13.37. Once again, my system is Dell XPS 630i. I see no reason to post other system specs since I don't know what exactly is at fault.

I have compiled both gocr and subtitleripper from [URL] and I am running into a problem with one of the scripts run from subtitleripper: pgm2txt. The error is:
Code:
andrew@skamandros~/Desktop/Labyrinth/subtitles$ pgm2txt -f en fauno
/usr/bin/pgm2txt: line 165: unexpected EOF while looking for matching `"'
/usr/bin/pgm2txt: line 179: syntax error: unexpected end of file
Support for this program is not available and development has ceased a while ago so I have had a look at the script itself and I cannot see the error in syntax.

Every since updating to kde 4.3, I have been experiencing frequent X crashes (1-2 times a day) whenever compositing is turned on (nvidia card). I was hoping that kde 4.3.1 would fix the issue for me, but no luck. So, I'd like to figure out what the nature of the problem is so that I can report it to the appropriate (ahem) authorities, but am not exactly sure how to dig up any useful information. The Xorg log didn't *seem* to have anything particularly informative to say about it (just a few lines about nvidia_drv.so).

I run a Laptop (Mint 17.1), which is connected to a Debian 8.1 server over a LAN. The systems are connected through a router. Both of them show no problems when working independently and when doing work on the internet. Also, ping works fine (no lost packets, no delays!) from Debian to Mint. However when doing a ping from the Laptop (Mint) to the Debian server, I experience frequent packet losses and timeouts. In fact, a "first" ping may lose the first 20 to 30 "tries". Thereafter, if I repeat pings immediately and quickly one after the other, they might in geral not lose packages or show delays. Ping to and from the router also works perfectly in either direction!
Of course, functions such as ssh or samba-sharing are hampered as well by this behaviour. Also, if I DO in fact manage to connect to the Debian server via ssh, my console (KDE 14) is freuqently "locked" (i.e. - doesn't show my input for a while) but in the end DOES show the characters entered and gets processed o.k. (eg. when doing an "ls"-command). Both systems are at the latest software-level and I just finished installing Debian 8.1. The situation was the same on Debian Wheezy, however.

In LMMS, pretty much any time where pressing a key or button is supposed to do something, it can crash. Regardless of what made it crash, it always dies in the exact same way: The window just disappears, and I get the line "Segmentation fault" in the console. Usually it crashes within 15 minutes of normal use. Not even 6 hours after I downloaded the program, I had given up trying to use it. Over the next week, a couple other programs crashed with segfaults.
Most of them only crashed once (among those was Firefox). So, of course, I'm now beginning to think that maybe the problem is not with LMMS, but rather with Ubuntu. I've had very little luck getting most of these programs to crash a second time, but I did find reliable ways to reproduce the crash in LMMS and Golly, so I got debug logs of those (with backtraces and steps I took to reproduce):
Code:
What I did to make LMMS Crash:
1. After starting LMMS, created an instrument track using the Oh Synth preset (under LB302)
2. Opened the tool window for the track.
3. Dragged my cursor back and forth across the keys on the virtual piano at the bottom of said window to play them.
4. Within 3 seconds, it crashed.
Starting program: /usr/bin/lmms

Code:
What I Did to make Golly Crash:
1. After starting Golly, loaded the example file "Still-Lifes/eaters.rle".
2. Alternated between Space (Next Generation) and Ctrl+Z (Undo), holding each for about 1 second.
3. Within 15 seconds, it crashed.

I've tried using different governors for CPU (Conservative, Ondemand, etc.), and these crashes continued to occur. I also tried using a different kernel to no avail; the crashes occur both on 2.6.32-21-generic and 2.6.31-17-generic. How to fix whatever's causing these segfaults.

First post here, some really useful information on the site especially for a Linux newbie like myself.
I installed Ubuntu 10.10 after Vista on a Compaq desktop not dual boot and with a completely blanked HDD, which although not the most powerful of desktops has an intel pentium dual core processor and a decent enough graphics card, enough to surpas the system requirements for linux anyway. After installing there has been alot of freezing, particularly when loading alot of programmes. It either freezes the screen completely so I cant do anything whatsoever and have to turn the computer off manually, or flashes a blank screen then goes back to the page I was previously on. However when it does this, the mouse works, but nothing responds, no keyboard shortcuts or anything. I have a feeling it may be the computer not the OS.

Is there a way under linux to find out directory with frequent writes and/or deletes?
I'm using Ubuntu and recently bought SSD. I moved /tmp to ramdisk and did some other tweaks to avoid wear. But I was wondering if there's a way to pinpoint hotspots in filesystem where files are often written. For example webserver's log directory with many appends every minute or user's download directory where he downloads gigabytes of stuff only to be moved elsewhere soon after finishing.
I came across inotify which could probably do the trick but it seems it'd require lot of scripting which I'm not very familiar with

I have an MacBook Pro 3,1 running Karmic ( 9.10 ) 64bit. The kernel is 2.6.32 patched to use the BFS scheduler. I am having issues with the touchpad and the keyboard. On occasion they stop working. It is possible that I have damaged hardware. However I would like to see if any other users report similar issues before blaming the HW. At the end of this message is what dmesg reports when this occurs.Often, before the touchpad and keyboard completely stop working they appear to stutter. They work fine then stop responding briefly then start working again.

I experience X crashes on a frequent level. First it happened with the current stable nvidia 180 driver, and the nonfree flash player (....., vimeo, etc). I replaced the stable nvidia driver with the 180-dev driver which fixed the flash problem. However it still happens that the X chashes without any reason or pattern. One time it crashed the moment I wanted to save a PDF file to my HDD downloading it with Firefox, another time it crashed while idling. I use an Alienware M15x with a nvidia 260M. Compiz is installed and active. Which other data or logs do you need?

Since upgrading (fresh install) to Lucid, I've been having to go through disk checks about once or twice a week on boot. I'm not sure why Lucid thinks it needs to check my disk so often. I looked into it a bit, and found a command that was supposed to stop disk checks happening so often.
Code: sudo tune2fs -i 2w `mount | awk '$3 == "/" {print $1}'` is supposed to set it to 2 weeks. I used "/home" too as I have home on a separate partition and didn't want that to be checked too. All was fine until I booted up to find another disk check today. It can sometimes take over half an hour to finish and C to cancel doesn't always work either.
I always shutdown cleanly, unless Ubuntu completely locks up, which happens maybe once every six months (although it did happen yesterday, but I have rebooted it a few times since then with no checks happening until just now). Is there a way to just disable checks completely? I wouldn't mind running them manually every now and then, I just don't want to do it as often as Lucid does.

I'm having issue with my wireless connection. I'm not sure if it is the WPA security causing the issue, but I randomly lose connection to the router. The network manager then scans for available wireless routers for a bit before trying to reconnect to my router and asking for my wireless password again.

I am experiencing frequent crashes for my browsers (FireFox, Opera, Konquerer). It doesn't seem to be related to the amount of tabs I have open, sometimes it will crash on 1 tab, and sometimes it is fine to have 20 tabs up. In addition to this, some flash videos hang after 3 secs.
PC spec:
OS: SuSE 11.2 (x86_64)

I made a fresh installation of Ubuntu 10.10 (64 bit) on a Sony PCG-81112M, the graphic cards is identified by lspci as "nVidia Corporation GT216 [GeForce FT 330M]". Quite frequently everything but the mouse pointer freezed on the screen, I found no way to recover from these situations but to restart the computer using the power button.
I decided to install the proprietary driver (as this is the recommended driver, I was confident this would solve the problem). As a consequence the system now hangs on boot after showing the Ubuntu 10.10 inial logo/text. I could start in recovery mode, but I'm not sure to which driver I should try to change to. I really need no fancy 3d stuff, just a robust computer to which I can attach and detach an external screen.

I have three machines networked to my desktop which run a bunch of simulations in parallel. As they're running, I connect to them via SSH and screen to keep an eye on the runs and look at the output. They stay usually connected for days at a time. The SSH servers and client are running Fedora 14. Yesterday one of my coworkers accidentally yanked the plug on one of the servers while it was running. When I powered it up again, I started getting some odd connection problems. I couldn't connect to it via SSH initially because I got the Remote Host Identification Changed (RSA host key changed) error. I deleted the key in .ssh/known_hosts, which allowed me to connect, but it denied my password. I then logged into that machine locally, restarted sshd, and removed .ssh/known_hosts again. Now I can log in via SSH without problems. However, the connection dies with a "Write failed: Broken pipe" error every few minutes (as opposed to the other two machines, which stay connected indefinitely).
So my questions are:
1.) why would a power loss affect the behavior of the SSH server?
2.) why do I keep getting broken pipes now?

I have a problem in Ubuntu 10.04. The bug is well know which makes the hard disk head to park often (2-3 times per minute) that's dangerous for the drive in the long term and annoying for me (click-click-click).I found out the "ugly-fix" for old Ubuntu version which was :hdparm -B 254 /dev/sda instead of 128. It works. The problem is that it doesn't remains (when restart/standby/ac connection-disconnection).I found a script well known too :Code:1) make a file named "99-hdd-spin-fix.sh". The important thing is starting with "99".2) make sure the file contains the following 2 lines (fix it if you have PATA HDD):
#!/bin/sh
hdparm -B 255 /dev/sda
3) copy this file to 3 locations:

My laptop has a DVD/RW (It is both dash "-" and plus "+" able...whatever that really means.) drive. When I want to burn media,I grab a fresh disk from my bulk supplies and load it to the drive.Trouble #1 -- Software fails to recognize the fresh media as blank.I start the burn processing ... chug chug chug ... and something goes wrong.
Trouble #2 -- Software has some trouble writing the fresh media. I grab another fresh disk and repeat, often 2 or 3 times, before I get a successful burn. Can someone tell me why I have so much trouble with getting a media burn without all of the retry activities? How do I discover exactly what is going wrong? I don't find logs or similar that explain the troubles. I use both K3B (my fave) and Brasero.

I created a thread about a problem a I had with my hard disk clicking whilst idle little while ago and I may now have stumbled upon a possible solution. The strange thing with the problem is that Ubuntu/Kubuntu didn't cause this problem but Opensuse 11.2 does.
I installed Fedora 13 to have a glimpse of what all the fuss was about and noticed that I had the same problem (hard disk clicking whilst idle ~ every 20 secs or so). Now there's a wiki on this subject and a few bug reports: [url]
Problem Description
Some ATA harddrives perform very frequent head unloads under Linux significantly shortening their lifespans. Root cause
The inactivity timer for head unload is configured too aggressively either via ATA APM (Advanced Power Management) feature or other non-standard means. Such aggressive settings are very fragile to changes in IO pattern and under Linux many such drives unload their heads only to re-load them shortly. Note that this relentless unloading/reloading cycle can also be triggered under Windows by installing programs which can alter the IO pattern (e.g. certain vaccine programs which runs in background).
Now two of the listed models with this problem are basically identical to my model (Dell Inspiron 1520) and basically share the same hardware: Dell Vostro 1500 and XPS 1520.
The workaround listed is to:
set APM to 254
Furthermore, there is a script: Storage-Fixup which can also be downloaded from opensuse software search. Indeed there is a report of this for a Vostro 1500: Gmane Loom
The report suggests looking at: Disk Power Management - openSUSE which lists a method to create a configuration file to management disk power management:
My question is whether I could download the storage-fixup rpm [url] has a description of it and it can be found: Software.openSUSE.org) and install it to (hopefully) solve the issue or should I follow the method given in: Disk Power Management - openSUSE
to set APM to 254:

I have a 10.10 machine where it has taken to refusing to logout of one specific user account. When I choose logout/restart/whatever from the possible options, it takes me to the main login screen (with the drums) and it shows thet that user is still logged in. The only way, once this occurs, to rid myself of this is to sign in as an administrator and run shutdown -r 00 under sudo. Then it reboots. (Using the admin account to choose restart/shutdown also returns me to the mail login screen where that unpriv'd user is still logged in.) (The machine is fully up to date.)

I'm having an issue with a PC ( Gateway GT5220 ), with Ubuntu 64 bit 8.04 installed. There was Vista originally installed in it.
Now, every time I execute shutdown from GUI or command line, the PC reboots and never shuts down on its own, I have to keep pressed the power button for a few secs to power it off. It's very irritating and I don't know wether it's a Ubuntu or a BIOS issue.
