It did end up applying, but did not have any effect.  Looking at the patch
again, I see that it appears to only affect CONFIG_SMP, which I am not
running (and in fact it adds a build warning for the !SMP case).  So there
was not much chance of it fixing anything, I suppose.

Any other ideas?  I don't have a serial console, and the trace scrolls off
my console, so I don't know if any debug printks would help.  Would it help
if I copied the entire panic message entirely, including the Code section?
I can try that the next time it happens.
