<pre>I keep having much of this problem, found this bug, and could reproduce it in
gdb. I hope this trace can help.
I'm running on Gentoo x86_64, Win7 guest. I've been having this problem for a
while, but didn't think to look in the system logs for qemu up until now.
Currently 3.19.2 kernel, 10.4.4 mesa, nvidia drivers, etc.
I don't get BSOD on next boot, but rebooting doesn't work. Win7 also dies all
on its own from time to time, I wonder if it's related, so I'm going to leave
it running under gdb for a while to see. Anyway, for the reboot issue:
Program received signal SIGSEGV, Segmentation fault.
