Well ... the prior bug reports with this are in aic79xx, and there there
were no significant code changes between the working and the non working
versions. The aic7xxx driver has been fairly significantly changed but
all in the area of setup and initialisation.

This one looks like a sequencer error, possibly induced by a flakey bus.
Apparently it actually managed to recover once, which is surprising for
the aic driver, but then it died a second time around. There actually
was a sequencer change (backport from aic latest driver) that could be
responsible. However, it's in both 2.6.12 and 2.6.13.
