the datasheet is wrong. QL1040 supports 64bit addresses via DAC,
otherwise it wouldn't work on SGI Origin and SGI Octane systems.
Your patch breaks them (verified on a Octane).
So your problem might not be in the scsi driver, but a PCI setup
problem for the bus of the 32bit PCI slot in your system. If this
bus doesn't support DAC it IMHO shoulnd't allow 64bit PCI addresses.
