Re: [Qemu-devel] kqemu version 1.3.0pre5

I'm still getting a kernel panic running a Linux guest kernel with
-kernel-qemu. I'm using kqemu-1.3.0pre5 and
qemu-snapshot-2006-03-27_23.

The guest kernel is a precompiled Fedora Core 4 kernel, version
2.6.14-1.1656_FC4. It works fine with kqemu in non-kernel-kqemu mode.

Any hints for how to track this problem down?
