2.6.38-rc2: Uhhuh. NMI received for unknown reason 2d on CPU 0.

[George Spelvin]

Since upgrading to -rc2 (-rc3 is compiling right now), I've been getting
complaints at irregular intervals.  This didn't used to happen with 2.6.37.

It's an old crappy 1.6 GHz P4 (HP Pavilion) with an ASUS P4B266LA
motherboard and a 2001 Award BIOS.

Should I bisect this, or does someone know what might be happening?

Thank you!
