[2.] Full description of the problem/report:
This machine is a news server. It runs INN 2.2 21-Jan-1999. The machine
is unusable after the oops. Last oops I was able to capture. INND died
but the box was functional.
[3.] Keywords (i.e., modules, networking, kernel):
[4.] Kernel version (from /proc/version):
Linux version 2.2.10 (root@monster) (gcc version 2.7.2.3) #14 Mon Jun 14
22:54:45 EDT 1999
