Hi, I am not sure if this fault is not related to 133451 and 133128 but I have serious performance degradation with suspend2-sources >=2.6.16. System boots up quite fast but after a while performance goes rapidly down. There is pernament CPU compsumtion 5-30% even in idle state and TOP reports at it is taken by procesess that usualy take almost 0. see here: Tasks: 97 total, 12 running, 85 sleeping, 0 stopped, 0 zombie Cpu(s): 6.4% us, 77.9% sy, 0.0% ni, 2.5% id, 0.0% wa, 3.2% hi, 10.0% si Mem: 377156k total, 303032k used, 74124k free, 22352k buffers Swap: 340160k total, 0k used, 340160k free, 168508k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13083 root 15 0 150m 15m 3776 S 16.4 4.2 1:37.61 X 13205 ondrej 16 0 37080 18m 13m R 13.6 5.1 1:07.23 kded 13213 ondrej 15 0 33024 16m 11m S 9.9 4.6 0:47.87 kicker 13187 ondrej 15 0 37080 18m 13m S 5.9 5.1 0:24.71 kded 13218 ondrej 15 0 50692 30m 16m S 4.6 8.2 0:28.28 superkaramba 13219 ondrej 16 0 30624 15m 10m S 4.0 4.1 0:04.16 konsole 14578 ondrej 20 0 0 0 0 R 4.0 0.0 0:00.13 grep 14547 ondrej 16 0 2116 1096 820 R 3.4 0.3 0:00.66 top 14589 ondrej 17 0 1644 488 424 R 3.4 0.1 0:00.11 df 14580 ondrej 21 0 0 0 0 R 1.5 0.0 0:00.05 cut 14576 ondrej 16 0 2776 1164 996 S 1.2 0.3 0:00.04 bash 14582 ondrej 19 0 1872 572 504 R 1.2 0.2 0:00.04 ifconfig 11703 root 15 0 3632 900 664 S 0.6 0.2 0:04.64 parallel 11934 haldaemo 17 0 1736 600 524 R 0.6 0.2 0:02.27 hald-addon-stor 13196 ondrej 15 0 9924 5476 4192 S 0.6 1.5 0:04.48 artsd 13209 ondrej 15 0 28848 13m 9752 S 0.6 3.7 0:08.39 kwin 13211 ondrej 15 0 29976 15m 11m S 0.6 4.1 0:05.19 kdesktop 14581 ondrej 20 0 2776 1172 996 R 0.6 0.3 0:00.02 bash 14583 ondrej 20 0 0 0 0 R 0.6 0.0 0:00.02 bash 1 root 16 0 1464 500 440 S 0.3 0.1 0:00.81 init 10989 root 16 0 1600 660 548 S 0.3 0.2 0:01.96 cpufreqd 13216 ondrej 16 0 26868 11m 8388 S 0.3 3.1 0:01.74 klipper 13505 ondrej 16 0 50692 30m 16m S 0.3 8.2 0:00.28 superkaramba 14586 ondrej 19 0 2780 1168 996 R 0.3 0.3 0:00.01 bash 2 root 34 19 0 0 0 S 0.0 0.0 0:00.62 ksoftirqd/0 Disk access performance is also degradated: usual figures: /dev/hda: Timing cached reads: 556 MB in 2.00 seconds = 344.80 MB/sec Timing buffered disk reads: 24 MB in 3.38 seconds = 17.10 MB/sec with 2.6.16 suspend2: /dev/hda: Timing cached reads: 556 MB in 2.00 seconds = 277.80 MB/sec Timing buffered disk reads: 24 MB in 3.38 seconds = 7.10 MB/sec dmesg goes here: Linux version 2.6.16-suspend2-r4 (root@trinity) (gcc version 3.4.5 (Gentoo 3.4.5-r1, ssp-3.4.5-1.0, pie-8.7.9)) #2 PREEMPT Fri May 19 18:54:59 CEST 2006 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 00000000177d0000 (usable) BIOS-e820: 00000000177d0000 - 00000000177e0000 (reserved) BIOS-e820: 00000000177e0000 - 00000000177e8000 (ACPI data) BIOS-e820: 00000000177e8000 - 0000000017800000 (ACPI NVS) BIOS-e820: 0000000017800000 - 0000000018000000 (reserved) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 375MB LOWMEM available.

There is also thread in http://forums.gentoo.org/viewtopic-t-459294-highlight-kernel+performance.html Please let me know if you need more.
Please use "New -> Gentoo Linux -> Component: Ebuilds" in future. Infrastructure is not the correct addressee.
Please try to reproduce with gentoo-sources-2.6.16-r7 (and if problem persists, vanilla-sources-2.6.17-rc4).
I reproduced with gentoo-sources-2.6.16-r7 with the same - same performance problems results. that I tried vanilla-sources-2.6.17-rc4 and also faced same prerformace issues. Than I tried 2.6.16 vanila from kernel.org and everything looks ok.
In the future, please reopen a bug when you provide the requested information.
We need to figure out which kernel version introduces the bug then. Please start by seeing if you can reproduce the issue on gentoo-sources-2.6.16 (the first 2.6.16 release). Configure it as close to vanilla as possible, e.g. do not include vesafb-tng and fbsplash.
OK. Here we go with some results. As per your advice I used gentoo-sources-2.6.16 and completely removed vesafb-tng and fbsplash. So no frame buffer console was used and I faced the same performance issues. Yes I think there must be something in gentoo patchset because 2.6.16 vanila does not have this problems. Please let me know what more I could try to remove from the kernel. I don't have an idea what to try now.
Odd. Are you definitely using the same .config file for each kernel that you try? The next thing to investigate is which exact patch is causing the problem. The patches applied to gentoo-sources-2.6.16 (initial release) are found in these tarballs: http://dev.gentoo.org/~dsd/gentoo-sources/tarballs/genpatches-2.6.16-1.base.tar.bz2 http://dev.gentoo.org/~dsd/gentoo-sources/tarballs/genpatches-2.6.16-1.extras.tar.bz2 Apply them in ascending numeric order to a clean and fast 2.6.16 kernel, a few at a time, until you figure out which one causes the slowdown. If you need to step back at any time, you can revert patches in descending numeric order using the -R argument to patch. If you need more specific instructions, just say.
Sorry I have to admit, that there is something wrong in my .config. I am still not sure what it is but when I started with the patching I found that I have performance issues also on vanilla 2.6.16 without any patch. As soon as I discovered it, I tried config from 2.6.16-r1 kernel with natural performance, applied it to 2.6.16 and I achived normal results. Than I tried to apply it to 2.6.16-suspend2-sources and it works too. So my conclusion is that I have migration problems with .config file between 2.6.15 and 2.6.16. There is many new definitions and if some of them is used in default it can make conflict, that makes the system performing like this. I know I am not the one having these problems, so I attached two config /working and non working/ files for your awareness but I am not sure if you are interested in it. If not plase close this case.

Created attachment 89297 [details] Used for 2.6.16-suspen2-r4 This config gives the kernel normal performance.
Here are some suspects from the bad config: These were enabled in the bad config but not in the good: CONFIG_SLOB: This is only for embedded systems. It does not scale to normal system use. CONFIG_BLK_DEV_GENERIC: The generic (slow) IDE driver may be claiming your hardware I do not recommend reusing old configs for new kernels. It is fairly common for them to bring up problems like this one. Reusing configs is OK for minor upgrades (e.g. 2.6.16-r2 to 2.6.16-r3) but not for actual kernel upgrades (e.g. 2.6.15 to 2.6.16) -- too much changes each time for this to be viable for the majority of users.
Thank you. CONFIG_SLOB was the root of all this. Using config from 2.6.15 made CONFIG_SLOB enabled and CONFIG_SLAB disabled. Just to correct this gave me normal performance back. Thanks for bug learning lesson.
