Hi all.


I've had problems with the aic7xxx card missing an interrupt on a 
dual processor poweredge 4200.  Unfortunately, this is still the case
with the latest -current.

It seems it misses interrupts so it then thinks that it hasn't received a 
reply from the card and it dumps the card register state.

However, while running in uniprocessor mode, it works.  In SMP mode it
fails.  I suspect this may be an APIC problem.

Unfortunately, the box is old enough not to have ACPI so unfortunately
I cannot try that ...

I've attached a dmesg of it while running in SMP mode with the card dumping
state.  this is NetBSD 2.0_BETA (I took this on the serial console last time)
but I've checked and it is still the same with the latest -current.

Any help on how to fix this (or that it cannot be fixed ...) would be 
appreciated.  In a previous life it ran redhat linux (2.4.x) in SMP mode, so it
must have worked somehow ...

	-- geoff.
