According to backtrace, system tried to reference address 0xc while
sending final flush command to the drive. ATA has no other shutdown
actions except this, so any contexts and states should not be lost in
any case. And as soon as your drive was detected, the controller is
probably operable. Haven't you seen any other ATA error messages during
boot or later?
If my i386 kernel is more or less coherent to your's,
ata_promise_sx4_command+0x39 address where it have crashed means
caddr_t window = rman_get_virtual(ctlr->r_res1);
line, and especially 'ctlr->r_res1' part. So looks like
struct ata_pci_controller *ctlr = device_get_softc(gparent);
returned NULL there. But the same technique used by many other ATA
drivers without problems, so I am a bit surprised.
Is the problem continuously repeatable? Does the controller operates
well all other time before shutdown? Are you sure that you have rebuilt
your kernel correctly?
