FWIW, back in the days I tried to use the parport, I've got an endless 
sequence of irq_unbalanced(..) messages, until I killed the task which 
was trying to access the parport (i.e. lpr). This was with 2.4.17 on a 
A4000.

But it did never oops when using the parport!

So maybe with 2.4.17 it was at least still half working.
