Hi, could you please try the following patch:
http://www.xtrarom.org/patches/powernowk8.diff
hmm, this seems wrong. the current code also seems
wrong..it appears to want to run on the attaching cpu
since it does things like:
status = rdmsr(MSR_AMDK7_FIDVID_STATUS);
i think the right answer would be to have this code run
when the cpu is fired up in i386/i386/cpu.c:cpu_hatch()
after CPUF_GO is set (same in amd64/amd64/cpu.c.)
