I agree that you have ample reason to suspect
driver problem, not hardware! :-)

I tried to locate my old posting, but somehow could not find
it in my local folder, but if I recall correctly
mine is certainly the PCI parity error which appeared
somewhere after the PCI_COMMAND_PARITY line in the
startup message below.

Again, possibly the high(er) speed of I/O might
affect the electrical cable condition, but
given the hardware you have, I trust that
you have high-quality cable and terminator, and
so maybe someone who is familiar with the driver code
can help us here.
