Comment # 80 on bug 1063638 from Ulrich Derenthal

Apparently my laptop has a similar problem (with Opensuse Tumbleweed). It seems
to occur weekly (on Mondays) and sometimes lasts for more than an hour.

After reading many of the comments here, it remains unclear to me whether there
are several different issues (and if so, how to find out which might affect
me), whether there is a workaround, and how to proceed.
