Ah! :) (hint.ahci.0.msi, of course!)

That appears to work:

    ahci0: attempting to allocate 1 MSI vectors (8 supported)
    msi: routing MSI IRQ 263 to local APIC 0 vector 58

I?m doing a scrub of the pool now - it was a resilvering activity that caused it
to crash and burn before, so I?m hoping that scrub should emulate the same load.
I?ll report back when it?s finished.
