[Bug 1255777] Re: [Toshiba Ultrabook STi UB 1401] kworker process takes up ~95% of one CPU after suspending and resuming
Contrary to what was previously ocurring, this problem started arising
now even when the computer has not been suspended. It's getting worse.

Title:
[Toshiba Ultrabook STi UB 1401] kworker process takes up ~95% of one
CPU after suspending and resuming
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
On my computer, everytime I suspend and resume, a process appears
called kworker and takes around 95% CPU until next reboot. Contrary to
what I've seen around, the lid doesn't have to be closed and it
doesn't affect the next suspending.
