Hi,
I have a 1 GHz Coppermine PC with 512 MB RAM, and it is failing to boot with the nmi_watchdog=1
option. This kernel was rebuilt after doing a "make mrproper". The dmesg log follows:

I think we've fixed that now. Len: if so, has that fix been sent in for
2.6.24.1?

Oh yes, 2.6.23.14 is fine with nmi_watchdog=1. (This is on a UP machine with a SMP/PREEMPT kernel,
BTW. "Just for fun.")

No, I don't know of any 2.6.24 oops fixes that aren't already in 2.6.24 --
at least I can't think of any right now.

Actually on closer inspection I'd say that acpi_ns_get_device_callback is
stack gunk and it isn't involved here.
It isn't clear (to me) where in this mess we disabled interrupts around the
set_cpus_allowed(). Chris, if this is repeatable it would be helpful to
set CONFIG_FRAME_POINTER=y which hopefully will get us a cleaner trace,
thanks.

So it's a CONFIG_SMP=y kernel on a single-cpu machine?

I'm in a twisty maze of kernel versions, all different. Looks like we're
calling setup_nmi() under local_irq_disable() somewhere but I got lost
chasing it down. We can wait for the code to stabilise a bit I guess -
it's harmless at this stage in bootup.

It is unclear to me what clocksource (if any) your machine is using.

And I assume this happened because you just aren't getting any clock ticks.

Correct.
