please try CONFIG_ACPI_THERMAL=n and see if you can still reproduce this issue. Created attachment 8686 [details]

ill try CONFIG_ACPI_THERMAL=n; and shall revert back to you later. i recompiled the kernel like this and it has not given me problems. its probably one of the modules thats causing this. thanks for all the help though... miraj. # # ACPI (Advanced Configuration and Power Interface) Support # CONFIG_ACPI=y # CONFIG_ACPI_AC is not set # CONFIG_ACPI_BATTERY is not set CONFIG_ACPI_BUTTON=m # CONFIG_ACPI_VIDEO is not set # CONFIG_ACPI_HOTKEY is not set # CONFIG_ACPI_FAN is not set # CONFIG_ACPI_PROCESSOR is not set # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_IBM is not set # CONFIG_ACPI_TOSHIBA is not set CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y # CONFIG_X86_PM_TIMER is not set # CONFIG_ACPI_CONTAINER is not set No guys, CONFIG_ACPI_THERMAL=n has not helped... it actually acts up when i start compiling anything else. it still runs at those cpu %ages even after whatever im compiling finishes... my mistake, also happens in the previous config i posted earlier. Hi All. I dont know what ive done. but it seems to be behaving now. i installed quite a number of applications and it seems to be working, like gnome-power-manager, acpid and laptop-mode-tools and many others not sure which one actually worked... hmmmmm, how can i file this as a problem between the computer and the chair? :-P I shall monitor this for a while. its been almost an hour since it has not gone gaga on me. Thanks for your help. Miraj. Problem still valid, reproduced under Linux integral 2.6.19.1 #1 PREEMPT Thu Jan 4 23:16:06 CET 2007 i686 GNU/Linux Same notebook model (just under debian - etch). Used to happen under 2.6.16, 2.6.18 and 2.6.17. It starts acting up whenever doing a cpu intensive task, keeps going for a good while and stops without any apparent reason. A reboot fixes the problem (temporarly), as does disabling acpi on boot (this fixes it for good, but obvoiusly doesnt count as a fix, does it ? :) ). Bugfixes suggested in this report dont help. Requesting this bug to be reopened, or a working description of a configuration change be provided (since its marked 'invalid' i assume this is not a true bug, and there is a solution available somewhere). please try patch from bug #5534 Thanks for the quick reply Alexey, this looks like it might do the trick. But it doesnt compile with 2.6.19.1 with: drivers/acpi/osl.c: In function 'acpi_os_execute_notify': drivers/acpi/osl.c:589: error: 'struct acpi_os_dpc' has no member named 'work' drivers/acpi/osl.c:589: warning: type defaults to 'int' in declaration of '__mptr' drivers/acpi/osl.c:589: warning: initialization from incompatible pointer type drivers/acpi/osl.c:589: error: 'struct acpi_os_dpc' has no member named 'work' drivers/acpi/osl.c:668:50: error: macro "INIT_WORK" requires 3 arguments, but only 2 given drivers/acpi/osl.c: In function 'acpi_os_execute': drivers/acpi/osl.c:668: error: 'INIT_WORK' undeclared (first use in this function) drivers/acpi/osl.c:668: error: (Each undeclared identifier is reported only once drivers/acpi/osl.c:668: error: for each function it appears in.) drivers/acpi/osl.c:669: error: 'struct acpi_os_dpc' has no member named 'work' drivers/acpi/osl.c:674:52: error: macro "INIT_WORK" requires 3 arguments, but only 2 given drivers/acpi/osl.c:675: error: 'struct acpi_os_dpc' has no member named 'work' drivers/acpi/osl.c:620: warning: unused variable 'task' Also - the last chunk in the patch failed, and a most were moved. But thats something minor that i can actually handle :) To the point: would it be too much if i asked for a working one ? This is really bothersome, and forces me to reboot my laptop frequently. Any help will be greatly appreciated (should you guys want to test anything on this brand/model machine, just let me know, im fine with it as long as swsusp works on that kernel :P). Cheers, Lukasz Latest patch in 5534 is for 2.6.20 kernel, for your 19 you should use patch from #180 commit, sorry for not telling you earlier :) Thx alot :D Here goes... hopefully - something. Patch applied, already running the patched kernel. Ill get back once this happens again, or in a week if it doesnt (i expect it to happen at least once every 24 hours, but lets be safe - im adding it to my organizer now :) ). Thanks again for the quick responce :) Well, still no love, it just happend again after waking the laptop from sleep (induced by acpitool -S). Something has changed thou: kacpid is eating 60% of my resources, while kacpi_notify is chewing away happily at the rest of them (cpu load is 90-100% again). Sadly - the bug is not resolved(nor is it invalid). hi, i made this invalid as it can be resolved without tinkering with the kernel. install laptop-mode-tools (and/or) laptop-detect for your distribution (apt-get install laptop-mode-tools laptop-detect)? i switched from gentoo linux to ubuntu (evolution-exchange is a better experience on ubuntu from what i think) on the same laptop and this problem has gone. im currently on Linux kernel version 2.6.17-10. let me know if this helps. oh.... the trickest part to install is the wireless drivers. let me know if u need help. miraj. Well, resume of your machine should be fixed in #7122. Hi, sadly - no love. It just happend again with a kernel with the 7122 patches applied. In fact, it seems to be happening faster after a wakeup the previously, and happens almost every time. Im thinking the pattern occurs when i put the laptop to sleep with the AC still plugged in and wake it up without the AC. laptop-mode and laptop-detect did nothing usefull. I already have wifi via ndiswrapper, and it happens regardless if i have the module loaded or not (i checked this a couple of times). Ideas ? More info needed ? Should i start a new bug ? (its still the same problem as i understand it). Created attachment 10082 [details] update AC state after a resume >Im thinking the pattern occurs when i put the laptop to sleep with the AC >still plugged in and wake it up without the AC. This sounds interesting. Maybe update the AC state after a resume will make some difference. Can you have a test with this patch? :) This problem just hit me after upgrading from Ubuntu Edgy (2.6.17) to Feisty (2.6.20-16-generic). The symptoms are the same, kacpid takes 2/3'ds of the cpu and kacpi_notify takes the rest. There are lots of other Ubuntu users with the same problem: http://ubuntuforums.org/showthread.php?t=462057 https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/75174 Since this bug report seems to have been rejected though there's clearly a bug here, head on over to bug 8274, which is still open and covers the same problem. |
