My Friday and Saturday kernel builds have both hung at boot.  I'm
am getting the following message:

Timecounters tick every 10.000 msec
ad0: 39205MB <Maxtor 6E040L0> [79656/16/63] at ata2-master UDMA66
ahc0: PCI error Interrupt at seqaddr = 0x9
ahc0: Data Parity Error Detected during address or write data phase

and then it hangs.  Only reset will get a response.

Booting the previous kernel, I get these messages at this point:

Timecounters tick every 10.000 msec
ad0: 39205MB <Maxtor 6E040L0> [79656/16/63] at ata2-master UDMA66
SMP: AP CPU #1 Launched!
da0 at ahc0 bus 0 target 0 lun 0
... and so on, to a successful boot...

There haven't been any changes to ahc, that I can tell, so perhaps
this is related to the PCI changes.  I will back out those changes
and see if that fixes it.

Here is the relavent boot infomation for this machine:
