qemu freebsd failed with kqemu loaded
I tried to virtualize freebsd using qemu with kqemu but failed, both 6.2
release and 7.0 current, and both w/ and w/o acpi. The failure log said:
Fatal trap 9: general protection fault while in kernel mode
cpuid = 0; apic id = 00

stack pointer = 0x28:0xc1420cfc

However it works without kqemu, but as the nature of freebsd, without
kqemu is painfully slow.
I'm running sid, qemu version 0.9.0+20070816-1 and kqemu version
1.3.0~pre11-6.1. I've been encountering this problem since kqemu 1.3.0~pre9.
Surprisingly, the same qemu and kqemu version under gentoo works
out-of-box, and works under Windows as well. So as a first look the
problem is probably sit in Debian side. I can provide further
information if necessary. Thanks in advance.
