[BUG] XFS crash using Realtime Preemption patch
From: Nathaniel W. Filardo
Date: Sat Dec 18 2004 - 20:30:32 EST
Hello all.
Using 2.6.10-rc3-mm1-V0.7.33-04 and TCFQ ver 17, I get the following crash
while trying to sync the portage tree, though the system seems stable
under interactive load (read: an rm command went OK prior to this crash).
Machine is a 933MHz transmeta laptop with IDE disk.
Any more information you need?
