Hi,

I installed QEMU 0.8.1 and kqemu-kmod kqemu-kmod-1.3.0.p7 today on
6.1-PRERELEASE from 6 March.  I tried running it with the
"-kernel-kqemu" option for increased performance.

It did boot up my WinXP guest rather quickly, but then it soon got into
some kind of extreme busy state.  The load went up, the X display was
not refreshed any more, just the mouse still moved.  I could escape to
the console and found lots of

        May 11 13:04:44 hunter kernel: npxdna: fpcurthread == curthread 46 times
        ...

messages.  I then had to kill qemu.

It does run ok without the "-kernel-kqemu" option.  Any idea?
