Subjectoops with 1.99.14 and isdn
Well, I admit it: I was playing with ISDN (a line, a board and noone to
talk to...) Anyway, when I started two version of ucu - a terminal
emulator similar to cu - and dialed the same isdn number - mine - from two
different sessions, I got the following

that ksymoops translates as:

Using `/usr/src/linux/System.map' to map addresses to symbols.

Curious thing is that after the oops (I still haven't rebooted), few
messages from the isdn controller go to the console as well as being
logged by syslog (debug).

I will now reboot. I expect that the messages will disappear. If the
isdn4k people are interested in the messages, I can send them some...

Ciao
Carlo
