I still get this with latest 2.6.27.9 kernel + kqemu 1.4.0 + latest svn 
co.

I tried to dump the linux console to stdio, but there is nothing 
significant on the console. It really seems to be kqemu returning an
unrecoverable error.

I tried disabling acpi, apic, lapic on the install kernel cmd line, 
nothing workarounds the crash. Only -no-kqemu seems to avoid the crash 
but then the install never finishes as it decompresses a random .deb file 
for more than 2 days (depends on the run). The .deb file is part of the 
base install so i can skip it.

Is there a way i can help finding the error ?
