Do you know if your CPU supports the CPUID instruction? What is the exact CPU model (manufacturer, etc). What does /proc/cpuinfo say? What happens if you make a change something like this: *** vg_startup.S 17 Oct 2003 13:24:40 -0000 1.18 --- vg_startup.S 6 Nov 2003 22:01:54 -0000 *************** really_start_up: *** 112,117 **** --- 112,118 ---- # cpu or not. movb $0, VG_(have_ssestate) # assume sse-disabled movl $0, %eax + jmp get_fpu cpuid cmpl $1, %eax jl get_fpu # we cant do cpuid(1) ?!
