My linux box just froze for ~ 15 seconds. I was in X. The pointer
froze, the capslock key didn't toggle the capslock light, etc... It
seems to be fine now that it's warmed up again. The logs showed:
Sep 2 11:46:41 blinky kernel: stuck on TLB IPI wait (CPU#0)
Sep 2 11:46:41 blinky last message repeated 23 times
This is in kernel 2.2.5 from a stock RH6.0 setup.
Is this a known bug? If not, should I start running a more recent
kernel (possibly with debug mods) & see if it happens again? If so,
has it been fixed in a newer kernel?
