[Bug 409801] New: kacpid / kacpi_notify using an entire CPU
https://bugzilla.novell.com/show_bug.cgi?id=409801 Summary: kacpid / kacpi_notify using an entire CPU Product: openSUSE 11.0 Version: Final Platform: i686 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: led@lenday.com QAContact: qa@suse.de Found By: Customer A lot of the time (not always) these two processes are running and using 100% of a CPU between them. After reboot they seem OK, then seem to build up although I haven't fully proven this. Platform is a Dell D820, O/S is SuSE 11.0, all updates installed. I haven't customized any power management settings. Desktop is KDE 3.
From things I find on the net disabling acpi would probably fix it but this is a notebook and power management matters...

It turns out that this is stimulated by a suspend to disk / resume. That is why I just saw it sometimes but it seems to be completely reproducable that it occurs if and only if I suspend. I did try rmmod battery when it was in the condition and it made no difference. I rebooted and removed battery, then suspended and resumed. The condition reoccurred. The BIOS version on the box is A07, I believe that it is fairly recent. I am using the Nvidia proprietary driver for video, it used to have power management problems but I thought that they fixed it. And yes, they are kernel threads, they always have PIDs of 12 and 13 and they will not die... Thanks for looking into it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

With the branch kernel I had two problems. The first time I did suspend and resumed, it didn't come back up. Console 1 ended with the maessage "Image loaded successfully" and it hung, console 7 had a cursor blinking in the upper left and nothing else worked. I don't think this is a new problem, I have gotten failures like this occasionally with the previous kernel as well. The second time it did come up. But kacpid was back into its loop. So I backed it out. Anyway, it looks like my problem is solved, thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Removing the patch is not an option we need to fix it. The first attempt or say a backport pointing to this direction seem to not have succeeded. Just to be sure the branch kernel you tried had the modifications already you can verfiy with: rpm -qp --changelog kernel-default-XY.rpm (on the downloaded rpm) or rpm -q --changelog kernel-default-2.6.25... (on the installed kernel, must match the exact version).
