I assume it just locks up after this?
It looks like the parity error isn't propagating upwards like it should.
What did a 2.6.11 boot sequence show for this (i.e. did the internal
aic7xxx DV configure the device narrow)?
I suspect the attached patch might fix this in the core driver, if you
could try it out.
Thanks,
James
