Per, Markus, is this reproduceable for you? How can you trigger this?

Yes, it is reproduceable, just start the system in runlevel 5 ( KDE 3.5) and wait a few minutes. No special trigger needed (there is a builtin USB cardreader, but no memorycard inserted) . All KOTDs 2.6.27.7 show the problem. 2.6.26.6 is fine. -- 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.

Can someone confirm that CONFIG_PREEMPT_VOLUNTARY causes it by compiling and running the same kernel with and without it? Regarding comment #8, please blacklist ehci_hcd and try again. @everybody: please leave a few lines before the BUG in the log.
