If you're not able to reproduce it with that, I'll build a kernel-desktop debug equivalent. The main issue is that -desktop does a lot more aggressive preemption, so it shakes bugs out sometimes. I'd like to confirm that it's not caused by that first. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
