No. The change was done by peter on December 12 (or was it 14) '99,
when he made the PnP stuff default. It took me a long time to figure
this out (and many rebuilds). When I first reported it to Warner he
said that he was seeing the same thing and committed a fix. The fix
fixed things for his card but not for mine - he probably has little
incentive to fix the problem unless I send him my card, but that'll
mean I'll have to buy another one as this is my second-most-important
machine :-/

I would have thought that's a different problem. Mine definitely
seems to be the result of an intrusive probe on an ISA PnP card,
whereas I thought all 2940s were PCI (maybe I'm wrong there - is
yours PCI ?).

I've tried my config with exact matches of the irq/dma/io stuff and
with just ``device aha'' to no avail. I can also turn the PnP probe
on and off to reliably show it failing and succeeding. The PnP id
matches the 1542CP id in aha.c (sorry, can't say which for sure right
now as my dmesg has scrolled out of buffer range).
