Also, any attempt to use a parallel printer resulted in the message:
kfree_s: Bad obj 00000000
I assume that this is unrelated to above problem and to make sure that this
did not effect the other, the second oops was generated on a freshly rebooted
machine. Parport and lp are modules.

Slip is compiled in kernel, ppp is modular. Kerneld is being used, but does
not seem to be a factor. This problem is very repeatable. Diald is not most
rescent version, but that should not be an excuse for a kernel crash. If
someone wants my .config just ask.
