This may be completely irrelevant, but we have a 9550 card running
RAID 5 with a 'prominent non-Linux' operating system that suffers from
the same symptoms (and 4 others that have never done it). We've heard
from our vendor (and 3ware) that there are some upcoming firmware
releases (looks like August) that might help. A 3ware tech told me
that the controller reset happens when communication between the
driver and the firmware times out, which appears to be exactly what is
in your error message.

Meanwhile, we just cross our fingers and thank our lucky stars the the
server in question is in our local office and not one of our
non-tech-staffed remote offices. There are unsupported pre-release
firmware downloads available if you like to gamble. I have not had the
courage to install the beta firmware on our servers. I have not used
3ware with CentOS, but I don't think this is a CentOS issue.
