jmide/ahci/interrupt panic on boot

[Gary Duzan <gary%duzan.org@localhost>]

   Has anyone else seen this or have any idea what might be going
on? Some debugging code shows that chp->ch_queue is null, but from
the code it looks like it should be set in ahci_attach. This was
working fine in 4.99.55 around March 10.

   Thanks.

                                        Gary Duzan
