** novelty ** The first time for the ksoftirqd 100% cpu usage problem several stack dumps were taken (by Alt-PrnScr-L) to let you see in which execution state the CPU was. So just have a look at this.

The 2.6.37 traces are useless. The 2.6.34.7 ones are helpful though. Also /proc/softirq clearly shows that some kind of shit schedules a tasklet way too often. I'm attaching a patch to track that down. Also I'm building a kernel to test and it will appear at: http://labs.suse.cz/jslaby/bug-465039 Watch for tasklet_action in the logs when this happens. Maybe there will be false positives. Then I'll increase the limit. Let's see. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
