Bug Description

Trying to use plip to provide networking via a parallel cable consistently breaks the kernel.

When set up, it all works fine for a period (although with occasional timeout errors). Then this starts happening:

After this, the system will either (a) keep running with plip still going, (b) keep running but plip will freeze, or (c) lock up.

If the system stays running, eventually this happens:

The system then becomes highly unstable and I need to reboot it (using SysRq).

This is with Ubuntu breezy, kept up-to-date. The parallel port is set up as ECP (the next thing I need to try is setting it to EPP to see whether that makes a difference).
