Robert,
I have able to reproduce very easily on:
processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 2 model name : AMD Phenom(tm) 8450 Triple-Core Processor stepping : 3
using:
$ perf record -g ./hackbench 10 Time: 0.415 [ perf record: Woken up 3 times to write data ] [ perf record: Captured and wrote 0.706 MB perf.data (~30841 samples) ] $ dmesg | tail [ 418.946001] Uhhuh. NMI received for unknown reason 3d on CPU 0. [ 418.946001] Do you have a strange power saving mode enabled? [ 418.946001] Dazed and confused, but trying to continue
This is with 2.6.36-rc4-tip as of this morning from tip-x86.
