Ohhhh, this is a different issue. Sorry. As a hack, try changing
'FIRST_MSI_INT' to 512 in sys/amd64/include/intr_machdep.h. The issue
is that some systems now include more than 256 interrupt pins on I/O
APICs, so IRQ 256 is already reserved for use by one of those
interrupt pins. The real fix is that I need to make FIRST_MSI_INT
dynamic instead of a constant and just define it as the first free IRQ
after the I/O APICs have probed.
