Here is a cpuid dump from inside the guest and dump from more recent version of cpuid, in which you can see a bit more detail. The later contains data for a single CPU, because the others are the same.
Reproducible on qemu 1.0 and 1.2. with guest os Fedora 17, Debian 6, Debian Squeeze and Windows 2008 R2.
Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
[Expired for QEMU because there has been no activity for 60 days.]
