Title:
Same bug, starting today with the updated 3.10.1-031001-generic kernel
on Ubuntu 13.04. I suspect my ipw2200 wifi to be the source of the
problem (the driver seems to be slowly falling behind, it is getting

Had this problem with a 12.04 that had been upgraded from 11.04 to 11.10
to 12.04 32 bit. I finally reinstalled new 64 bit 12.04 and the problem
persisted. For me it was gpe11 that had a value of 4200. I followed

Without doing anything to my machine, the problem went away. However,

usual. But the 3rd on
I have this bug coming back and bite me again.
Obviously, kworker hogging CPU can be caused by multiple causes. Since
this bug report is generic in nature, maybe it should be converted as a
