Hi.

I'm successfully running Windows 2000 guest on qemu (linux host) with
kernel-kqemu, and the speed is excellent.  However I can't get linux to
run as a guest (still linux host); no matter what kernel or kernel
config I create, it always BUGs at the same point:

If kernel-kqemu works with linux 2.6 for anyone, could you email
a .config that works?)

Thanks,
