: When I start it outside and then connect the card it will detect and : configure it correctly. OK. This is a HUGE clue. One that shouldn't be overlooked :-). What it is telling me is that FUNCTION interrupts aren't getting through, but STATUS interrupts ARE getting through. I'll have to go re-read my two TOPIC data sheets to make sure, but I think that the TOPIC chips, especially the older ones, have a number of knobs for function interrupts that are not in the standard bridge chipset. Please refresh my recollection: Did this used to work with 5.4? IIRC, I did some work to fix o2 micro hangs that disabled the function interrupts during card insertion by routing them via IRQ 1 (which the o2micro actually doesn't route, so they just disappear). Maybe that work around had bad effects for the TOPIC95B that you have? Warner
