Could you boot with nmi_watchdog=0 and when you get a shell prompt, run

I am curious to know if this is lockup detector related or the perf
subystem related.

OK, with 2.6.39-rc5-git4:
$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-2.6.39-rc5-git4
root=UUID=96c96a61-8615-4715-86d0-09cb8c62638c ro lapic
nmi_watchdog=0
Once I'd installed linux-tools-2.6.39, perf ran fine and I've
attached the perf.data output.
Thanks. I assume no softlockup warnings showed up after running the perf
command?
Cheers,
Don
Correct, no soft lockups warnings after running the perf command.
Arthur.
