===============================================================================
>Description:
When booting this system with an SMP kernel all disk activity
on the 39160 PCI HBA results in a timeout. After instrumenting
the aic7xxx driver, it is plain that interrupts are not being
delivered. In the SMP boot case, ahc0 is given irq 17, ahc1
is given irq 18, and ahc2 is given irq 10. A UP kernel from
the same sources boots correctly.
>How-To-Repeat:
Boot a PR440FX with a multi-function PCI device.
>Fix:
My guess is that we're missing another workaround for a
broken mptable, but I don't know enough about the MP
spec to determine exactly what is wrong nor how to
correct it.
