Revision 1.36 of sys/pci/ide_pci.c causes DMA problems and a panic on
my laptop:
[...]

Unfortunately, I don't have a serial console attached and the dmesg
buffer is cut off after any ide_pci messages on the bad boot. I'll be
able to get that information tomorrow if the cause of this problem
isn't clear without it. I do have the full messages from a successful
boot (the only change was backing ide_pci.c to 1.35):

I really don't know crap about what's going on in that part of the
kernel, but I'll do whatever I can to help track this down. Or
perhaps it will be intuitively obvious from this report.
