My system freezes when I run some disk write operations. For example results of "time emerge-webrsync" on 2.6.12-r4 kernel allways more than with 2.6.11-r11 kernel. Results: for 2.6.11-r11: 4m22.575s 0m31.067s 0m27.072s for 2.6.12-r4: 4m43.236s 0m35.267s 0m35.844s At repeated experiences results repeat. Reproducible: Always Steps to Reproduce: 1. Run one of kernels and run emerge-webrsync (I have gentoo mirror in LAN) 2. Reboot to the kernel 2.6.11 runlevel 3 3. Login as root 4. Run "time emerge-webrsync" 5. Store results & reboot 6. Select kernel 2.6.12 runlevel 3 7. Repeat items 3, 4, and 5 for this kernel. Actual Results: for 2.6.11-r11 (exp. #1): real 4m21.732s user 0m30.243s sys 0m27.856s for 2.6.11-r11 (exp. #2): real 4m22.575s user 0m31.067s sys 0m27.072s for 2.6.12-r4 (exp. #1): real 4m43.236s user 0m35.267s sys 0m35.844s for 2.6.12-r4 (exp. #2): real 4m44.083s user 0m37.276s sys 0m30.732s Expected Results: I think that difference between results for both kernels must be not above than difference between results of different experiences for one kernel.

My root filesystem is reiserfs.
I'm not sure if this is related, but recently one of disks in my software RAID-5 array died. While rebuilding the array after replacing the faulty drive, the box was simply unuseable, with load avarage reaching 150... AMD Athlon(tm) XP 2200+, gentoo-sources-2.6.12-r4, mdadm-1.12.0, SiI 3114 SATA + Seagate ST3200822AS drives with reiserfs. I don't remember that I would ever have such a high load, even when I was initially setting up the array with some older kernel version, it was at least 5 times lower.
Please attach kernel configs for both 2.6.11 and 2.6.12 Please be more descriptive when you say "my system freezes"

Created attachment 63523 [details] Configuration for my 2.6.12-r4 kernel
Then I say "my system freezes" I mean: I can change virtual consoles. This action do not slower than other time. If I try to run on over virtual console application or load/save file (fo example: "vi /etc/fstab") then this console hangs while the emerge-webrsync will not finish. If I try switch to the X-session then screen blanks and freeze while emerge- webrsync finish... emerge-webrsync I use only for example.
Ok, for both kernels, please post/attach: (where /dev/hda is your primary hard disk) "dmesg" output "hdparm /dev/hda" output "hdparm -I /dev/hda" output "hdparm -Tt /dev/hda" output

Created attachment 63532 [details] dmesg & hdparm results for kernel 2.6.12-r4 Sorry about previous "comment"... I am only want to edit attachement.
Thanks for posting all that. Can't see anything wrong after a quick look. If its not too much trouble, could you also post /proc/interrupts from both kernels please? Also, you should test vanilla-sources-2.6.13_rc3 and see if the problem still exists there.
Created attachment 63592 [details] /proc/interrupts for kernel 2.6.11-r11
Created attachment 63593 [details] /proc/interrupts for kernel-2.6.12-r4 When I load kernel 2.6.12 to get /proc/interrupts file I check for freeze by emerge-webrsync. I try to open vi, nano, mc and some files at running time, but system work correct (thus I try to repeat freeze operation, but can't)... I in perplexity... I think that is need to stop discussion about freezing... Continue about different time of execution (ie. resource usage).
I make 5 experiments: kernel-2.6.12-r4: real 4m58.013s, 4m36.420s user 0m34.979s, 0m31.150s sys 0m31.150s, 0m31.832s kernel-2.6.12.2: real 4m29.836s, 4m33.776s user 0m35.506s, 0m35.946s sys 0m30.806s, 0m30.535s kernel-2.6.11-r11 real 4m36.778s user 0m31.143s sys 0m26.753s I think that 2.6.12-r4 kernel hardly more slowly than 2.6.11-r11.
Dont quite understand your last comment. You are saying it now looks like the gentoo 2.6.12 patches are causing the slowdown, since vanilla 2.6.12 is fast again?

May be kernel-2.6.12 litle slow than 2.6.11. But now I work with 2.6.12-r4, and no problem. I think that problem were in configuration.
