Hi,
I'm having a very similar problem with the same laptop running 2.6.36_rc6 but
this time it's a kworker which consumes ~100% CPU.
I first tried rmmod'ing all the modules but it didn't help. Then I built the
kernel with some ACPI/PM verbose flags turned on and found out an infinite
number of the following message was written in kernel log:
scsi host1: __pm_runtime_resume() returns 1!
I then passed "on\n" to all power/control files in sysfs but the logging didn't
appear. I disabled PM_RUNTIME to see if it was causing the kworker stuff, but
nope, it still continues.
Then I found this report and tried the gpe01 thing. Disabling it stopped the
kworker CPU consumation problem. When enabled the number of interrupts in
/sys/firmware/acpi/interrupts/gpe01 increases very fast.
But the problem is not fixed with the pcie_pme=off switch so I think the main
problem is different but the solution is the same.
Should I file a new bug report or can this be considered as a duplicate to
this?
How can I debug to find out the real issue?
Thanks
