Sorry to followup on myself - but the other people in this thread seem to have been expired locally and I lost my incoming mail playing with popclient ...

I have now read the assembler in irq.h that ACK_FIRST(mask,nr) expands to in 2.0.24 ... It doesn't seem to use the new argument (nr) to ACK_FIRST (any longer?. So the guy who plugged in 0 for the new argument in the call to ACK_FIRST in irq.c should have been right - but he reports that that functions wrong. Is the whole PCSP inclusion in irq.c just horribly broken by the changes since 2.0.0?
(and who in hell did that in a stable kernel release series :-).
Any assembler experts out there like to rewrite the PCSP irq.c code? I'll be happy to send it to them!
PS - I am reading the source over a dodgy modem, and it is possible I have misread - but I don't think so.
