Date: Wed, 16 May 2001 11:13:40 -0400 [thread overview]
Message-ID: <6B1DF6EEBA51D31182F200902740436802678ED2@mail-in.comverse-in.com> (raw)
If your PCI devices advertised they don't mind sharing the IRQs with each
other, ignore it if they're really capable of it. Otherwise, you'll probably
have to force one of the drivers and/or the bios to make them use separate
ones.
