The bug was reported for a tinycore 3.5.1 guest (linux kernel 3.6.33-3).
The iso image is available from 
http://distro.ibiblio.org/tinycorelinux/3.x/release/.
QEMU was running on XP SP3.

Other Linux live CD-ROMs (e.g. FC14) were reported to show the same bug
when run as guest.

APIC can be disabled (kernel parameter), without APIC there is no problem.

I see the same bug here with two XP hosts and also tried both timer variants
of current QEMU (without a difference).

I don't get the bug when running on a Linux host using wine.
