The system was a 2.0.36 with isdn as distributed in that kernel. This
thing was misbehaving (the synchronous ppp had a bug which I didn't know
then). On Jan 6th I had the following two oopses with an assumed lock
(well, I couldn't connect, syslog was dead till reboot the next
morning). Anyway, as this machine is a web server and mail server and
internet access point, I was quite surprised when I got the bill for
that month: the machine allegedley transferred 16GB (yep, giga) in 4
hours? To a host with isdn connection on its side?
Somebody can imagine such a behaviour? (the machine is hooked to a
34Mb/s backbone via standard 10Mbs ethernet)
The following logs are the two oopses, looks like kernel memory got
overwritten by something (I can see something like :11: in it, this
could be a string from syslog, as this happend around 22:11:xx)
