Hi Avi,
I'm still unable to reproduce this Fedora reboot failure.

That command looks like the vista cdrom scenario. To try and
reproduce the fedora reboot issue, I checked out 51a8ac6f of qemu-kvm
and ran:
qemu-img create -f qcow2 test-fc9 10G
qemu-system-x86_64 -hda test-fc9 -cdrom
../../iso/Fedora-9-i386-DVD/Fedora-9-i386-DVD.iso -m 512 -smp 2
This was with the bios.bin that came with 51a8ac6f. I selected all
default options (except I disabled "Software productivity tools" to
make the install go faster). The machine rebooted okay after the
install.
Can you retry this with the latest seabios git. If you are able to
reproduce, can you set CONFIG_DEBUG_LEVEL to 8 and post the log?
Maybe something in the log will help.
Thanks,
-Kevin
