[Lguest] unhandled trap 13

[Steffen Schulz]

Hi all,


my mail server is down right now, I'd appreciate if you would CC me via
pepe at cbg. dyndns. org


Grapper answered to my mail linking a patch to the nvidia module:
http://cyber-labs.org/patches/xen-nvidia/nvidia-binary-driver-100.14.11-1.patch

Yesterday, it stopped working after a few runs, but for now it seems to
be fine. (again, great work!)


However, my kernel appearrently lacks some ide drivers.
The .config is unchanged, I use it for host and guest. Platform is a
santa rosa macbook pro using intel sata. The disk image works with
qemu. This is what I get:
