When installing edgy in a new 64-bit guest, the guest always freezes when installing grub on the boot partition. This only happens with a 64/64 system. I can run the guest in qemu (as opposed to qemu-system-x86_64) and use grub to install itself, but if I try to do the same thing with qemu-system-x86_64 it hangs. After generating a trace file and stepping through the hang in gdb it looks like the guest is getting overwhhelmed with interrupts. It reminds me of a situation where some device driver is forgetting to issue an eoi and the interrupt line is remaining on, which means that the guest can never make any progress advancing the instruction pointer. I've placed a compressed log file at http://www.ncultra.org/qemu.log.tgz I'd be happy to spend some more time runnign this down - if anyone has any suggestions on how I should proceed I'd be grateful.
