OK - here's the patch to prevent arcnet oopsen on initialisation again. I've even made it print the right version number this time. (Thanks for pointing that one out, Avery.)
For the record: the interrupt handler was being invoked halfway through the init routine, before the init routine had a chance to set up the device structures. This puts a check in the irq handler to avoid the problem.
At some point, when I've not got three weeks to get my dissertation in, I'll take a closer look and make sure the interrupts don't get enabled until the init routine has finished. Then we can avoid the extra overhead in the irq handler.
For now, however, it's enough, especially as I don't have any ARCnet hardware any more to test with.
