Haven't had one of these for ages. This is with kernel 1.3.68.

System was sitting idle at the time, I was asleep. Last thing in the
/var/adm/messages was sendmail was sending me a message from news.

Changed vc then tried mc /var/adm to look at messages and it gave a GPF and
segmentation fault, changed to another vc and tried less /var/adm/messages
and gave another GPF and segmentation fault. I have then written down if
anyones interested.

Couldn't diassemble Code: as ksymoops says binutils too old :(

System is 486dx2/66, basically Slackware 2.1, gcc 2.5.8 - time I upgraded
eh?
