I'm using an Adaptec 2200S RAID card in an opteron system. It works fine
if I use 12G of RAM but if I have 16G it drops offline under stress (bonnie++
etc). Basically it's as if the whole array has been removed.
I first saw this problem under the suse9.1 2.6.5 kernel but the
problem is still
there under the 2.6.9 kernel as well.
I've tested the hardware, and this has happenned on 2 seperate systems so
it's not a hardware component problem.
Based on history with different RAID cards, I tried turning off node interleave
and harddware IOMMU on the Arima motherboard, but that hasn't made a
difference.
Has anyone seen this problem before?
regards,
dan carpenter
