OpenSUSE Hardware :: AHCI Causes That Udev Eats To Much Cpu
Apr 23, 2010
/sbin/udevd --daemon eats about 10-15% of cpu which is quite high. I found out that it is caused by AHCI. If I turn it off in bios, udev takes only about 0-1% of cpu (which I consider normal). However turning AHCI off is deadly for Windows Vista (I have dual boot) - it always ends up with BSOD. Actually, I don't even know what AHCI does. Of course I found some information on the net but I didn't found whether there are some advantages for me. Is it worth 10-15% of cpu (consequently shorter battery life)? On the other hand, I have no interest in changing my bios settings every time I boot to Windows so it would be much confortable to have it turned on all the time. The best solution would be to find out why AHCI does this and how to configure udev to avoid it. And I don't know how.I have OpenSuse 11.2, kernel 2.6.31.12
Maybe it's specific feature, but it does not seem right that within ~30 m to 1h 3gb of disk space on /home are gone due to I can't tell what exactly. Usually it happens while listening to music via vlc or browsing www (chrome and firefox). I got 3gigs of ram (95% in use under such conditions), and 1,5gb of swap that is not used at all by the system.Its a KDE.
I am using openSuSE 11.2 on a VGN-AR41L. I have also erased the preinstalled Home Vista (what a pleasure). Now to my problem. My system boots correctly but if I press the <ESC> key while booting I can see the following messages:
"Doing fast boot FATAL: mbcache module not found FATAL: ahci module not found " and the boot process continues normally.
Why this happens? Does this mean that I have a problem that I haven't discovered yet? Is it something that I can ignore? I am using SUSE Linux from version SUSE Linux 8 personal and although I am not a power user I have done my two desertions on this system and I am very happy with SUSE. I have bought SUSE Linux 8 Personal and SUSE Linux 10 all the other versions until today have been downloaded.
I have a HP Pavilion dv7-2230sa During boot I get a series of errors about ACPI and AHCI Conflicts, the result of which I have to dissable ACPI with acpi=off. However when acpi=off my wireless Broadcom b43 series refuses to enable the wifi. I just can't press the button that would enable / dissable the wifi.
The wifi is detected, the drivers and firmware are installed, however the light remains firmly in the RED.the ethernet works, sound works fine, There also seems to be an issue with the ATi/Radeon Driver being missing which is causing fatal errors at boot time and also some memory conflicts again causing fatal errors.
I have tried this laptop under opensuse 11.2 and now under opensuse 11.3M5 without sucsess - however to my dislike Ubuntu have managed to resolve this by accident between 9.4 and 9.10 but i wanna use opensuse not ubuntu i have asked them to tell me how they fixed it to share it with you but I am still plowing my way through their forum!
I have a little problem with my Samsung CLP-300 color laser printer (usb wired).Works as always, in opensuse (that means, nearly perfect, just color a bit problematic if printing in good quality).But since the upgrade (by means of zypper) to 11.3, in VirtualBox (not OSE, the one with USB support), the printer appears greyed (not the rest of USB devices), so that I cannot use it from the wndows inside VirtualBox (which is the only way to do a real high-quality printing).Does not seems to be a problem with VirtualBox (the resto of USB are properly detected and connected), but of any type of change that I cannot guess in the way udev manages the printer, so that this USB connection works in a different way from the rest (and from what it did in 11.2).That's why I post that here and not in software subsection. I think it's the proper place. If not, please, tell me.The dmesg output when I tur on the printer is the following one:
[352074.297027] usb 1-4: new high speed USB device using ehci_hcd and address 4 [352074.411969] usb 1-4: New USB device found, idVendor=04e8, idProduct=3272 [352074.411973] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
During the boot process the machine (Fujitsu Celsius M470) hangs about 4 min at udev:loading drivers. After that it continues and I can work with the OpenSuse 11.2 system without problems.I activated the debug log in /etc/udev/udev.confthen I see that it is doing a lot in that time, at the end I see the message:udevadm settle timeout queue contains: a long list of pci/usb entries (no entries in any log for this)
in the logfile I find:udevd-work[1071]: '/sbin/modprobe' (stderr) 'FATAL: Error inserting ipmi_si (/lib/modules/2.6.31.12-0.1-desktop/kernel/drivers/char/ipmi/ipmi_si.ko): No such device'there is no ipmi. how can I deactivate the loading of this module?

Boot from DVD 11.4 586 32 bit is fine. Loads up and offers me install, boot from HD, check media, firmware etc. Select text output, no acpi, check media. Linux kernel loads, then black screen showing progress in white text.
At "Starting udev..." process hangs. Eventually (several minutes later) message is returned about "worker" not able to read from "sr0" which I believe is the DVD drive which it has been using to this point.
I'm running 11.3 normally, udev is not a problem on boot from HD. The DVD media works fine on a Windows laptop showing "Starting udev... ok" and continues. Media checks ok on this machine.
I'm thinking that no matter what medium I use to install from, HD, DVD, net etc this udev problem is going to hit me again unless there is a hint I can pass to the bootup process.
After reading about other experiences with this issue I removed all the non-standard hardware and no difference. The DVD drive seems to be the issue. Bootup is already using it, and yet udev cannot find it.
I want to try the new 11.1. When I start the installation (x86_64 DVD), the startup is hanging. The last message is "Starting udev...". Keyboard is completely frozen, only reset button is working. Mobo is an Intel DG965WH with 4GB RAM and ATI Graphic card (ASUS1950pro). My opensuse 11.0 runs without any problems.
I've bougt a new pc (i5-2050k, Nvidia GeForce 560Ti) and wanted to install Linux beside Windows.But each Linux-distribution (exept the old ones from Mandriva) fails installing/starting als livecd/checking for installation errors/..... while initiating udev.Is there any known bugfix for this problem? Remind, there is just Windows, so don't give me any shellcode to execute
I have a powerful server with 24GB of ram and an Intel Xenon quad core processor that I'm using to run a bunch of virtual machines for an office on using VirtualBox. Lately there has been a problem though. If I run free this is what I get:
[Code]...
I have sysstat install so I ran sar -r on the command line and I found:
[Code]....
a little before 2:45 PM I had my RAM eaten. Going back through my brain I remember that at that time I ran the command VBoxManage clonehd XXXXX.vdi to clone one of my virtual hard drives. I tried this again to make sure that the VBoxManage clonehd command was really the thing that was eating my RAM and it was. My question is - how do I reclaim the RAM. When the process that ate all the ram finished (I think it's the VBoxSVC process) it just leaves me with all my RAM used. How do I free up the RAM without restarting the server?
I've install FC14 on my iMac 27" i7 and I'm having exactly the same issue I had with Ubuntu 10.10: acpid eats 90% of one Core all the time.With Ubuntu this issue was solved by updating but with FC14 no way, I can't find any solution.Right now I've turned off acpi and apm at boot time but this only let me use one of my four Cores.
which is approximately HALF the space than actually needed. Is this increase due to ecryptfs? Also I noticed that the hidden folders are not shown. Are the hidden files within the shown folders included in this list? How do I show a summary which includes the hidden files?
No doubt Psychess is a very nice game for playing chess. I was playing this game often. But one thing I observed today is Psychess starts to eat 100% CPU right after the moment we start the game. I came to know about this after observing the "System Monitor" applet graph on the panel. This must not be normal because it's common sense when developer develops a software they always consider the CPU usage.. Even when I develop scripts I always give a sleep after heavy resource usage. For the record, I installed DreamChess and it works fine.
I just got a USB bluetooth adapter for my Laptop. I'm running Lenny with all the lateset updates, on and Ispiron 8600. I went through and made sure I installed all the Bluez stuff (as far as I can tell anyway). I'm trying to use it with my Droid Eris and while I have been able to successfully recieve files from the phone in Linux, I noticed it seems a little buggy and I think it ma have something to do with the logs. Below is a sample. As you can see, one line keeps repeating continuously. Given enough time, it will fill the entire /var partition. When I remove the Blutooth, it stops.
I'm on 9.10 and I use huludesktop often to watch my Hulu queue. Every once in a while (and more so lately) the video freeze and the sound stutters. I then find that pulseaudio is taking 100% of a CPU (I have a quad core AMD 64bit machine). Killing pulseaudio causes huludesktop to continue without sound and a new pulseaudio starts up. I have to kill huludesktop and resume playback and then everything's OK, until it happens again.
Hey when i am downloading any thing using firefox or torrent, the downloading application eats up all the bandwidth, meaning i cannot browse the web simultaneously downloading anything , even Gwibber does not get updated...
If I use K9Copy to compress a 6.4 gb DVD to a 4.4gb ISO files, it heats up the CPU and the machine shuts off. When I do this with system monitor ON, I see 160% to 180% CPU usage. I guess this is due to dual core on my Gateway laptop.Then I installed DVD Shrink and tried the same by running DVD Shrink using Wine. This caused the same problem.I did not have this issue when I was using Windows Vista. Is there anything that I can do to avoid this problem?
I have a laptop configured with 2 partitions. The file ( Ubuntu ) partition which is about 30GB and a second 'data' partition of about 100 GB. On this data partition, I save all my digital photos ( about 20 GB ).When I installed Digikam, it seemed to compile its database on the smaller partition and left me with no space and error messages because of it.I managed to get rid of Digikam and regain space.Is there any way, I can re-install Digikam and stop it doing this ?
process kslowd00/kslowd001 it eats 60% of my cpu and 15% of my memory ... i can't kill it even as root.this process makes my computer slower than" IBM 704 running fortran programs "... I've faced this process using Fedora 14 and now with Scientific Linux 6(RHEL 6 recompiled) SL 5.5 didn't have this.
I'm working on a simple data processing script.My script uses a loop with getline to check for the value on the next line to decide if it's time to terminate the loop.This works dandy, but the problem is that getline eats that line, which then isn't processed by the rules in the remainder of the script (even though I want it to be). To illustrate what I mean, consider this simple gawk script:
I recently decided to install Ubuntu 11.04 on a 320gb hitachi sata hard drive. This is going into a new system with an Asus MB, AMD Proc, not sure if this matters. Anyway I can not set the bios to use ahci and see the sata drive. I can only use IDE mode with sata enabled. Asus support says to install ahci for os. If I boot into the USB install key and attempt to the install OS I receive a read/write error. I have another drive on IDE that has 11.04 on it and if I try to format the new drive and partition it with Disk Utility it fails with "Error formatting drive: error creating partition table: helper exited with exit code 1: error calling fsync(2) on /dev/sdb: Input/output error". I have tried to use dd and fdisk but I don't believe I need these until I do something else first just not sure how or where to look.
I'm doing a clean install on a new machine, and when I tried to boot the install DVD, ISOLinux gave me the following error:
Code: Could not find kernel image: linux After some experimentation, I found that switching the SATA mode in the BIOS from AHCI to Native IDE solved the problem and installation is proceeding normally.
However, I want AHCI enabled. (I think, unless someone has a compelling reason why I shouldn't.) My web-searching suggests that if the system is installed in IDE mode, it won't boot if I switch to AHCI afterwards. Is this a common problem? Is there a workaround? Is it a motherboard issue?
My ubuntu 32-bit 9.10 compiles kernel a few times, and now I realized my Win7 lines disappeared. First time when I made the dual boot system, I remember there is a line for Win7, and able to boot up Win7. And then I ran compilations 2 ~ 3 times, and now I see the lines gone. I know 'editing GRUB' is risky, and want to hear advice how to fix. - Actually I don't think I can edit grub.cfg file manually. In my Ubuntu Desktop menu, I still see and mount the Windows disk (physically different partition)
I'm running a pretty heavy-weight process (Rails tests) that involves several worker processes, in an effort to parallelize the runs. To measure the performance impacts, I run hdparm -T /dev/sda to give me the cached read performance. Note that the disk IO is not being measured, but the disk cache IO is. It works very well on my work machine (8-core Mac Pro running Ubuntu with 8GB of RAM).
The baseline is: honk4:~ $ sudo hdparm -T /dev/sda /dev/sda: Timing cached reads: 13224 MB in 2.00 seconds = 6616.86 MB/sec In the middle of the test run: honk4:~ $ sudo hdparm -T /dev/sda
Here is my problem: In short, it takes forever (6 min), and lots of prodding to get Ubuntu to boot. Im running a Toshiba NB305 netbook (Bios 1.40), set up for dual boot with 10.04 UNR. Windows partitions boot fine. Can boot 10.04 from USB stick.
Here how I try to boot: From grub menu select "Ubuntu, with Linux 2.6.32-22-generic" If it doesn't work, I run the recovery version, and then run the regular one again. Somehow that resets stuff.
If I change my sata mode from IDE to AHCI grub won't show (cursor goes to top left) when I power on my system. After that, I press the reset button and my grub shows ok.
So, to use AHCI I always have to use the reset switch button.
Using Ubuntu 10.10 with 2.6.35-23-generic - 64bits
I have been running a dual-boot, Windows 7 and Ubuntu 10.10 system with the disks set for IDE with no problems. I have just attempted to change the disk system to AHCI and, whilst I can boot into Windows 7, I am unable to boot into Linux and get the error: "Alert! /dev/disk/by-uuid/5d773307-a046-40fa-ba29-728611bc7eed does not exist" I am new to Linux so am unsure where to go from here. I have reverted to IDE for the moment and it boots Ok.
