kernel BUG at /usr/src/modules/kvm/mmu.c:307!
invalid opcode: 0000 [1] SMP
CPU 1
Problem is not there if running without mod probes on KVM and KVM_AMD
This happens after adding Microsoft Service Pack 4 to a Win2k install.
Package was running -no-acpi
Reproducible.
-win2k-hack makes no difference
It doesn't happen with earlier versions of win2k except when it was
installing the new KDE packages of windows on a pristine win2k service
pack 2 install.
Kvm works fine on other OS's except it does crash with the OS used for
Norton Ghost on e-machines XP image restore. It worked ok for image
restore running on freedos.
The same images run fine in a pure qemu mode.
OS is debian testing
