(Setup: 1.3.73. gcc 2.7.2. i386. diald is only interesting piece of
software, unless kerneld counts (slip as a loaded module). The slip link
was up at the time of the oopses.)

I had rebooted a few minutes earlier. Then, from cron 'netdate' got run.
This happened:

In mail, from my atrun, I got the message sent at 21:00:03 (ie before the
oopses):
/bin/sh: /usr/local/sbin/atrun: cannot execute binary file

However, the binary in /usr/local/sbin/atrun is just fine and worked after
the reboot.
