Hi All,
With kernel version 2.4.18 I have no problem to run pcnet32.o on the IBM
4694-205. Now I switch to kernel version 2.4.29. insmod crc32 : ok ,
insmod mii : ok , insmod pcnet32 : ok.
But if I run ifconfig (ifup) the system fries. Can't toggle the numlock
led. I find out that the system generates permanently interrupts from
the pcnet32 chip after calling request_irq (irq=9).

A possible solution could be (only tested on IBM 4694-205 and I don't
have other systems with VIA Tech.):
