Hi,

I'm using the aic94xx driver with a AIC-9410W controller (w/6 Seagate
Cheetah SAS drives) and am getting the following errors under heavy
load:

I am running kernel 2.6.25.8.
Controller firmware (/lib/firmware/aic94xx-seq.fw) is V30.

I have seen a few threads in the mailing list regarding similar errors
but none seem to lead to any kind of solution.

Does anyone have any leads I can follow? I'll be happy to try out
patches if anybody has anything.


Thanks a lot,

Patrick
