SubjectRe: Oprofile [still] doesn't work on 2.6.28-rc4 on certain CPU

Oprofile in 2.6.27 doesn't work on this system, as far as I know.

Yes, it seems to be very system-specific. As I have said in my original
mail, the machine we are seeing this problem on is

vendor_id : AuthenticAMD
cpu family : 15
model : 47
model name : AMD Athlon(tm) 64 Processor 3000+
stepping : 0

but on the other hand on the following CPU, the oprofile works with 2.6.27
and 2.6.28-rc4 without any problems, NMIs are coming flawlessly

vendor_id : AuthenticAMD
cpu family : 15
model : 4
model name : AMD Athlon(tm) 64 Processor 3000+
stepping : 8
