hmm. I have an FC 5.92 + yum updates running 2.6.18-1.2724.fc6xen with
xen that is completely unusable and gives me non-fatal kernel panics
and non-working networking (compared to 2.6.18-1.2724.fc6 not giving
panics and a working networking). xenguest-install.py also fails, and
the resulting kernels for xenu''s hang on boot.

Is this the planned kernel for fc6?

I also got various problems with this board and P-ATA. A "check media"
works fine and gives me the go ahead, but installation then gets "IDE:
unknown opcode" errors. I had to disable all cpu features and peripherals
to get through the install. Though some of this might be ASUS specific
and unfixable. It tends to pick weird (shared) IRQ''s for the P-ATA disk
controller. I am not using the SATA controller.

Seems all my bugs end up with Herbert these days eh? :)

Happened also with earlier kernels. BUG seems to be non-fatal, system seems
to work OK after that.
