For the record, I have never been able to successfully use qemu (w/ or
w/o kqemu, whether i386 or amd64) + 6.0 (up to RC1). It just panics
somewhere during the installation -- I'm able to get past sysinstall,
create my FreeBSD partitions, and proceed to doing a minimal install,
but somewhere in the middle of extracting, it just panics. I thought
it was caused by some of the ATA problems (w/c were supposed to be
fixed) but somehow I've not been successful. Some people also said
something about turning off INVARIANTS, WITNESS and friends but I
haven't checked whether this is disabled in RC1. Some people also had
the same problems in VMWare and 6.X though I don't know if they've
tried RC1 and whether that would work. Maybe those who have VMWare
report back?. I wanted to track this down but have been busy with
other more impt matters ;-(

This doesn't happen in 5.X, where I'm able to install it fine whether
in i386 or amd64, though the latter I've had to patch my tree because
there's no ed.

This is on FreeBSD/amd64 5.4Rp7

Thanks.
