Change 36551 by marcel at marcel_nfs on 2003/08/21 00:30:38
Aarrgghh. The interrupt issue on pluto1 and pluto2 are
very likely not driver problems. I forgot we have a hack
on the ia64 branch to deal with the fact that the non-
legacy interrupts used by the UARTs are edge sensitive,
active high. We really need to get that fixed in CVS...
