I see high cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. I tested various kernels from Ubuntu and mainline (3.5.0-x, 3.6.x, 3.7.0-rcx) and they all showed the same behaviour. This does not always happen.
I wasn't able to determine on which basis it happens. Some observations that may as well be wrong (duh!):
On some boot all is fine but once it shows, no matter how many reboots it does not seem to want to go away again.
The laptop seems to have to rest a while to have a chance that it won't happen.
If it does not happen a reboot will show the behaviour.

I saw similar bugs in various places but it seems that this can have a multitude of causes and the presented workaround or fixes did not apply to me.

description |
I see high cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. I tested various kernels from Ubuntu and mainline (3.5.0-x, 3.6.x, 3.7.0-rcx) and they all showed the same behavior. This does not always happen.
I wasn't able to determine on which basis it happens. Some observations that may as well be wrong (duh!):
On some boot all is fine but once it shows, no matter how many reboots it does not seem to want to go away again.
The laptop seems to have to rest a while to have a chance that it won't happen.
If it does not happen a reboot will show the behavior.
I saw similar bug reports in various places but it seems that this can have a multitude of causes and the presented workarounds or fixes did not apply to me.

I see high cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. I tested various kernels from Ubuntu and mainline (3.5.0-x, 3.6.x, 3.7.0-rcx) and they all showed the same behavior. This does not always happen.
I wasn't able to determine on which basis it happens. Some observations that may as well be wrong (duh!):
On some boot all is fine but once it shows, no matter how many reboots it does not seem to want to go away again.
The laptop seems to have to rest a while to have a chance that it won't happen.
If it does not happen a reboot will show the behavior.
I saw similar bug reports in various places but it seems that this can have a multitude of causes and the presented workarounds or fixes did not apply to me.

I see high (70-90%) cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2.
This does not always happen. On some boots all is fine but once it shows, rebooting does not make it go away.
WORKAROUND: Execute:
echo "disable" > /sys/firmware/acpi/interrupts/gpe13

I see high cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. I tested various kernels from Ubuntu and mainline (3.5.0-x, 3.6.x, 3.7.0-rcx) and they all showed the same behavior. This does not always happen.
I wasn't able to determine on which basis it happens. Some observations that may as well be wrong (duh!):
On some boot all is fine but once it shows, no matter how many reboots it does not seem to want to go away again.
The laptop seems to have to rest a while to have a chance that it won't happen.
If it does not happen a reboot will show the behavior.

I see high (70-90%) cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. This does not always happen. On some boots all is fine but once it shows, rebooting does not make it go away.
WORKAROUND: Execute:
echo "disable" > /sys/firmware/acpi/interrupts/gpe13
