I am not familiar with SMB systems at all, but I do know that once
my brother removed a floppy late one night without unmounting it.
The next day, suddenly I was overwhelmed with screens upon screens
of errors, and I was scared into ruining my 10 day uptime by rebooting.

Turns out that cron was running updatedb, which recursed into the /floppy
mount point, and the kernel flipped. Could the same thing be happening to
you? I know that by default, Redhat schedules updatedb for 1am-ish.

I just happened to notice that the date on the message was 1:41, which is
pretty close to 1am (given transmission time and time to type the
message, and such).

Still, this shouldn't cause a crash, but hopefully it will provide
insight to track the bug.

The first night in his new house, Gates told Walters, he watched a
big-screen TV that pops up out of a console in his bedroom. But things
went awry when he tried to go to sleep.

"He couldn't get it to go down, he couldn't get it to turn off, so he just
put a big blanket over the thing," she said. Gates has joked that
everything from light switches to music speakers goes on and off
unexpectedly in the house, which is run by a high-end PC network built on
Microsoft's Windows NT system.
