- Subject: kacpid hogs CPU on HP/Compaq nx6110
- From: Marcin Owsiany <marcin@owsiany.pl>

Package: kernel-image-2.6.11-1-686
Version: 2.6.11-5
Severity: normal
Shortly (it's hard to measure, but seems a few seconds) after applying
some load on the system (like "find / -type f|xargs cat|gzip -c|gzip
-dc|gzip -c > /dev/null"), the kacpid thread alone suddenly starts using
99.9% CPU (as shown by top), causing the whole system to become very
slow and seriously decreasing its responsiveness.
Sometimes even the load generated by system boot is sufficient, and
kacpid starts to hog the CPU during bootup, which makes it very slow.
Killing the load-generating task does not cause kacpid to release the
CPU (I waited over half an hour).
Specifying acpi=off eliminates the problem, but obviously is not a
solution, since the machine does not seem to provide APM interface
(modprobing apm says "no such device or address"), so I'm not even able
to monitor battery status. :-/
Attached: a dmesg dump (though no messages are generated when kacpid
goes crazy).
Google returns some similar cases on "kacpid cpu", but finds no fix. I
would happily help with debugging this problem, since I'm not using this
computer intensively. Just give me some suggestions / instructions /
pointers / references :-)
regards,
Marcin
