I checked the serial port log (I log the serial console from another machine,
to be sure to get these kinds of bugs even if they hit the network and/or
SCSI subsystems), and the only thing is that cron seems to have segfaulted a
time. This is unusual, but I take it it shouldn't crash the kernel in itself
(and it might be due to the result of some glibc up- and downgrading around
that time).
