Please only back out the part that early outs on no interrupt for us at all. There are some other changes in there which might indicate other problems, like interrupt masks set wrong and interrupts from the controller we are not but should be handling. I didn't realise that PCI devices were that badly designed. Sorry. Nick On Wed, 22 Aug 2001, Peter Wemm wrote: > "Vladimir B.
