This looks like some kind of stack corruption on 32-bit:
1472 if (kvm_enabled())
(gdb)
1473 host_cpuid(0, 0, NULL, ebx, ecx, edx);
(gdb)
Program received signal SIGSEGV, Segmentation fault.
0x081a2d60 in host_cpuid (function=10, count=1231384169, eax=0x0, ebx=0xadfc1914,
ecx=0xadfc1910, edx=0xadfc190c)
at /home/amit/src/kvm-userspace/qemu/target-i386/helper.c:1426
1426 asm volatile("pusha \n\t"
I don't see this on 64-bit. Investigating.
