Perhaps you can send me the patch? What do you changed in the driver?

that's fine

that's bad. Think it's the new SMP-Interrupt sheme.

did you tried FW 3a? (you can change this in the source code

strange... the jiffies are not increasing... normaly I have some delay when
loading the risc. This may be a timming problem. Oh no, not the good old f***ing
problem again...

The newest code (as of 4th April 1998) can be found in

http://schering.si2.uni-hannover.de/stuff/gaertner/WD719X/Linux/4.4.1998/
or
	http://sun1.rrzn.uni-hannover.de/gaertner.juergen/wd719x/Linux/4.4.1998/

this was my last version.

this seems to have to do with changes in the interrupt handler stuff. Nevermind,
until the firmware isn't loaded, no interrupts are created by the card.

Maybe you like to see the docu about the RISC at
