Kernel 3 Crashes on 4.2 unstable

[Andi Reinbrech <andi.reinbrech@darwinistic.com>]

Hi,

I am unable to pinpoint this problem; on an old core2duo Xen 4.2 and 
kernel 3.0 as dom0 works, but on a newer i5 (same distro, same packages, 
all "baselined") the crashes as soon as Xen finishes booting.

The crash happens before anything useful is written to the serial 
console, and causes the machine a complete warm boot with no exceptions 
or error messages.

I have tried nomodeset, but I'm not sure the kernel gets as far as 
initialising graphics, it may still be in the stage of unpacking the initrd.

I would greatly appreciate any pointers to try an help to debug this, or 
hear from other testers with similar experience.

The config of kernel 3.0 I'm using is the "vanilla" fedora rawhide 
version, 3.0 however, not the latest git rc.


Thanks & kind regards,
Andi
