I know why my system crashes, and it is not drbd's fault (drbd calls the
kernel panic because the lower level device SUCKS & dies :{ ).

However, to see why it was going down, on a fedora core 1 system, I had to
modify /etc/inittab and set the initdefault to 3 instead of 5.  With the
system in 3 (console instead of X) you can actually see the output of the
kernel panic or OOPS, even though it will never be in the syslog. After
changing it, I think running `init 3` will change you into level 3
immediately. the inittab affects you on boot.

As long as you don't need X running on the system ALL  the time, I would
suggest changing the inittab. At least then you can come back with more data.

Sorry this does not solve your problem, but I hope it helps get you on the
