[Bug 1107150] Re: B75 Chipset I/O Problems
Great to finally see this bug being worked on... I found a bunch of similar bug reports that were finally closed (and supposedly solved) because the original bug reporter ended up installing a 64-bit kernel instead. Here's what I found out so far: * This bug only affects writing to block devices. Read speeds are absolutely fine. It would be nice if the other people could confirm this! * This bug isn't related to the B75 chipset. I'm also experiencing this bug on a somewhat older chipset. I believe I'm using an Intel Q57 Express chipset but I doubt whether this is really relevant. * It will only trigger with the x86 kernel, not the amd64 kernel. * This bug _probably_ isn't limited to Ubuntu, Ubuntu is just the only distro that triggers it. I tested the following distributions: + Fedora 19 (32 bit) live cd (3.9.x kernel) - works fine + OpenSuSe 13.1 (32 bit) live cd (3.11 kernel) - works fine + Ubuntu 13.10 (32 bit) live cd (3.11 kernel) - doesn't work + Ubuntu 13.10 (64 bit) live cd (3.11 kernel) - works fine + Linux Mint 16 (32 bit) live cd (3.11 kernel) - doesn't work + Debian 7.2 (32 bit) live cd (3.2 kernel) - works fine I then went back to Ubuntu 12.10 32 bit (3.5.5 kernel) and confirmed that: + Running with only 8 Gigs of RAM gives me write speeds of 180-200Mb/sec + Running with 16 Gigs of RAM gives me write speeds of 160-180Mb/sec + Running with 32 Gigs of RAM gives me write speeds of 1.5-5.5Mb/sec I downloaded a stock 3.5.5 kernel tarball and compiled it with the ubuntu kernel config. The problem persists. There is a similar bug where pc's suddenly get terrible write speeds to block devices after waking up from suspend. This bug is caused by the fact that on some pc's MTRR registers change after waking up. After comparing Ubuntu, Fedora and Suse kernel configs, I noticed that Ubuntu is the only distro using the MTRR sanitizer. I disabled it but the problem persists. This definitely seems like an mm problem to me. I'd like to test the latest test kernel you've built but it's only available for amd64 (which never had the problem anyway). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1107150 Title: B75 Chipset I/O Problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1107150/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The problem is still an issue on i686 PAE kernel in raring. Got a Lenovo W520 Laptop with 24GiB of RAM. apt-get update takes several minutes. However I found a workaround as alternative to removing the memory physically. Add mem=0x2 kernel boot parameter in /etc/default/grub in run update-grub. This will limit memory usage to first 8GiB. After that even the boot became significantly faster. I found that without the workaround, the value in /proc/sys/vm/dirty_bytes is always zero.

@zaxx, Is it possible for you to reduce the amout of memory you have to see if you are seeing the same thing as Mark in comment #25? @Mark, so it appears the threshold is ~15GB of memory when things go bad? Also, the final v3.8 kernel[0] is now available. Would it be possible to test this kernel to see if this bug also exists upstream? Thanks in advance!

[Bug 1107150] Re: B75 Chipset I/O Problems
I was hunted by this bug to but observed some behaviour that might help... I required a i386 12.10 desktop install for some rebuilds. Therefore I installed it on a VirtualBox install on my Intel Core i7-2600 CPU @ 3.40GHz with 32GB RAM. At first it ran fine, but since I was in a hurry doing full rebuilds, I assigned more RAM and cores to the VM instance. Since then I am suffering the same performance degredation. At first I thought it just had to do with VirtualBox, so I installed the 12.10 i386 desktop natively on a build machine (Intel Core i5-2300 CPU @ 2.80GHz) with 16 GB RAM). After installation it ran fine for a while but then it also began to behave weird after I ran apt-get upgrade this morning. Since it ran initially fine on the VirtualBox instance, I recalled I changed the config. After restoring the settings to to what I think it used to be, all was fine. I have measured performance on my VirtualBox instance, varying ONLY the amount of assigned RAM. All other settings have been kept constant. I used time(1) to measure performance of 'sudo apt-get update'. I took 3 measurements, the times are below. I think it's safe to assume that the amount of RAM is of importance for this bug. I have not been able to test with a 64-bit kernel but it might not be reproducible with that. Please let me know if you require additional information about one of my systems.

[Bug 1107150] Re: B75 Chipset I/O Problems
I have installed 13.04 which runs the 3.8 Kernel and the problem persists. I tried testing as per your suggestion, but could not find a 3.8 kernel that would safely install on 12.10. Also I cannot get apport-collect to run on 12.10.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

[Bug 1107150] Re: B75 Chipset I/O Problems
apport information ** Tags added: apport-collected precise running-unity staging ** Description changed: I built a new system and installed Ubuntu 12.10. The system has the following specifications: Samsung 840 Pro 128 GB Gigabyte P75-D3 Intel i7 3770 32 GB Ram Western Digital 1 TB Black (mounted as /home) Western Digital 3 TB Green (mounted as /media/data_drive) The initial Ubuntu 12.10 install took almost 6 hours as transfer rates were very slow. After reboot everything appeared very fast. However when I did an apt-get update the download took 20 seconds and the processing of lists took 19 minutes. I had 12.10 installed on another computer which was working great (older Althon system) so I installed the drive and tested the new machine. It suffered the same performance problems. I installed Windows 7 and performed speeds tests, it reported great results. I installed 12.04 onto the 1 TB drive and it did not suffer the same performance problems. Everything ran great. I then upgraded 12.10 to 13.04 (January 27, 2013) and it too suffered from the performance issue. It appears that a change between 12.04 to 12.10 impacts AHCI based systems specifically running the Intel B75 chipset. I am not certain but I think that either the motherboard is misrepresenting something (that 12.04 ignores but it impacts 12.10) or the kernel is not detecting the system correctly. I created a couple of pastebins with data collected: 12.10 Install: http://pastebin.ubuntu.com/1561660/ 12.04 Live Disk (was checked against installed version and data is mostly the same): http://paste.ubuntu.com/1565140/ I have a thread on the ubuntu forums that may provide additional details: http://ubuntuforums.org/showthread.php?t=2104709 I also started an e-mail thread to the ubuntu-users mailing list: http://ubuntu.5.n6.nabble.com/Seeking-Help-td5010422.html I have done a lot of troubleshooting and I feel that the problem must either be the kernel or the bios misrepresenting information. In either case I am stuck without any idea of where to go next with the debuging and diagnoses path. - If any additional information needs to be collected, please let me know - and I will work to assist. + If any additional information needs to be collected, please let me know and I will work to assist. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + ApportVersion: 2.0.1-0ubuntu17.1 + Architecture: i386 + AudioDevicesInUse: + USERPID ACCESS COMMAND + /dev/snd/controlC1: bakers 1729 F pulseaudio + /dev/snd/controlC0: bakers 1729 F pulseaudio + CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found. + Card0.Amixer.info: + Card hw:0 'PCH'/'HDA Intel PCH at 0xf711 irq 45' +Mixer name : 'Realtek ALC887-VD' +Components : 'HDA:10ec0887,1458a002,00100302' +Controls : 39 +Simple ctrls : 20 + Card1.Amixer.info: + Card hw:1 'NVidia'/'HDA NVidia at 0xf708 irq 17' +Mixer name : 'Nvidia GPU 42 HDMI/DP' +Components : 'HDA:10de0042,14583553,00100100' +Controls : 18 +Simple ctrls : 3 + DistroRelease: Ubuntu 12.04 + IwConfig: + lono wireless extensions. + + eth0 no wireless extensions. + MachineType: Gigabyte Technology Co., Ltd.
