Forgot to mention: tcg appears to be unaffected - so far anyway.

Title:
qemu/kvm locks up when run 32bit userspace with 64bit kernel
Status in QEMU:
New
Status in “qemu-kvm” package in Debian:
Confirmed
Bug description:
Only applies to qemu-kvm 1.0, and only when kernel is 64bit and
userspace is 32bit, on x86. Did not happen with previous released
versions, such as 0.15. Not all guests triggers this issue - so far,
only (32bit) windows 7 guest shows it, but does that quite reliable:
first boot of an old guest with new qemu-kvm, windows finds a new CPU
and suggests rebooting - hit "Reboot" and in a few seconds it will be
locked up (including the monitor), with no CPU usage whatsoever.
Killable only with -9.
