MegaRAID problems

Hi there,

while the affected machine is not a Dell, I found reports of the same
problem for PERC cards and though I would ask here. We've got a customer
with a server which run fine for 1.5 years, then started to misbehave.
When we looked at it in the morning, all file systems where readonly and
we had I/O errors all over the place.

Once or twice I was able to grab the last log entries, they look like
this:

I performed an online update (machine is running SuSE 10.0) which gave
me a slightly newer kernel - the problem persists. I could not find
anything wrong with megamgr either.

Has anybody experienced this as well? Has anybode any hints or a 
solution? The machine is freezing every day now. :-( Maybe it's a
firmware issue (can't remember the exact version)?

Bye,

Tino.
