RE: Spontaneous Rebooting



Thanks for the tip about panic.log. Here's the entry that corresponds
with yesterday mornings reboot:

*********

panic(cpu 0): wait queue deadlock - wq=0x337220, cpu=0

Latest stack backtrace for cpu 0:
      Backtrace:

         0x0022C160 0x0003559C 0x0003547C
Proceeding back via exception chain:

Any Idea how to fix this? I see there are 2 other entries in panic.log,
one of which is cpu 1 and the other cpu 0.
