Title:
ksoftirqd/1 using 50% CPU or above
Status in “linux” package in Ubuntu:
Won't Fix
Status in openSUSE:
Unknown
Bug description:
ksoftirqd (ksoftirqd/1) is using 50% CPU or above when idle.
As others have already found out this is a bug with a module for a tv-tuner card. But I don't have such a card, and no such module is loaded.
