Hi,
Sometimes kacpi_notify_wq and kacpid_wq workqueues use a lot of cpu.
I'm using yesterday's tip. At times kacpi_notify_wq uses 30-50% of
my cpu and kacpid_wq uses 3-5%:
# uptime
12:49:54 up 4:16, 1 user, load average: 0.52, 0.55, 0.40
# ps -e | grep kacpi
189 ? 00:00:52 kacpid
190 ? 00:10:26 kacpi_notify
191 ? 00:00:00 kacpi_hotplug
This sometimes happens after a few hours of uptime; so this is
very hard to bisect (by the way, I think the same thing causes
the fans to work fullspeed sometimes when I reboot the machine).
I tried this patch to find out which of the callers of
acpi_os_execute() is the culprit:

Is there something I can do to trace the problem? dmesg and lspci

Hi Ali,
Please open new bug at bugzilla.kernel.org, for ACPI.
It would help if you provide name of your machine (make?) and acpidump output.
Do you know the kernel, there this problem did not occur (is it a regression)?
Let's continue problem discussion in bugzilla.
Regards,
Alex.

This is a hp-compaq 610 laptop.

The oldest kernel I tried on this machine was something after 2.6.32
and it had the same problem.
