My workstation (running the new kernel) did something similar
yesterday -- I left my office, came back a while later, and the
screen was blank.  I wasn't able to switch to a VC or log in
remotely (the system was pingable, and the first chunk of an SSH
connection would succeed, but not complete).  I was forced to
power cycle.

What seemed to be the same problem happened to our main file
server, still running RHL9 with kernel 2.4.20-31.9smp, the day
before.  With no X, I was able to type a username at the login:
prompt, but never got a password prompt.  The machine behaved
similarly with ssh connections.

There was nothing obvious in the logs.  I could figure out roughly
when the crash happened because nothing appeared in the logs after
that time.
