Dmesg log for 2.6.31-rc8 kernel been built on F12 (rawhide) vs log for same kernel been built on F11 and installed on F12
Previous 2.6.31-rc8 kernel was built on F11 and installed with modules on F12.
Current kernel has been built on F12 (2.6.31-0.204.rc9.fc12.x86_64) and installed
on F12 before loading under Xen 3.4.1.
Dmesg log looks similar to Michael Yuong''s ''rc7.git4'' kernel for F12.

[PATCH] Disable PAT support when running under Xen (v1).
The issue at hand is that any prolonged usage of radeon or nouveau driver
ends up corrupting the file system or we end up with mysterious crashes of
