Subject: [Bug 60644] MPT2SAS drops all HDDs when under high I/O

Hi .
Today , I ran some tests on all 8 drives connected to the LSI 2308 .
The results are rather surprising . The controller goes non-operational under
high READ workloads , while WRITE workloads always complete just fine .
I'll run more tests , but at this point I can safely say that heavy READ
operations (md5 checks , btrfs scrub , torrent files checking , etc) are the
problem , while heavy WRITE workloads (dd , copy , rsync) always complete
successfully .
I hope that can be useful in nailing this bug .
Thank you .
