Hello,
Here is a patch to fix the NMI watchdog problem on CoreDuo processor.
I think we still need Daniel's patch to make the error path (when you
are stuck) do the right cleanup.

kernel would get stuck du

Great. Can someone send a final version with proper Changelog and Signed-off-by
please? Thanks.

Here's a simpler patch that fixes the boot hang ..
We have to call off the IPI looping regardless of the check_nmi_watchdog

Bjorn,
It looks like we need to revisit the patch that makes the NMI
watchdog use the 2nd counter (PERFREVTSEL1/PMC1) for architectural
perfmon.
The Intel Core Duo processor has a bug (AE49) with the enable bit of the 2nd
counter not working. The Core 2 Duo/Quad processors also implement architec

You mentioned you have a development board with a dual Pentium-M.
What are the exact family/model numbers?
What Bjorn points you at below is a fix that applies to
Intel Core Duo/Solo (Yonah) and Intel Core 2 series but not to
regular Pentium-M (no architectural perfmon there).
