This looks like it probably has nothing to do with your module.  The
monotonic clock went backwards.  Also, it will only print once per boot,
even if the event happens again.

Is your system SMP?

No.

 Could you also send your config.

Attached.  (this is winbloze eudora, no inlining possible)

  And John will
probably want to see your dmesg output.

I'll send that off-line upon request. FWIW, it's not the original boot dmesg output however, but one a freshly booted system...

As luck would have it, just as I was collecting the data, there was a major explosion. Box was slogging through glibc make check, and when it hit the mutex tests in nptl, KaBOOM. Ding-dong-dead box... [reboot] oh my, seems repeatable. Guess I'll see if I can find my serial console cable instead of typing make install as originally planned :)
