I jumped into this thread late - can you repost detail on the specific

Okay, expanding the receiver list. :)
To recap:
I'm running 2.6.27 with LVM over software RAID 1 over a pair of SAS disks.
Disks are WD9001BKHG, controller is Intel C600.
Just curious what driver are you using with the C600. The upstream
driver for C600 didn't get accepted until 3.0-rc6 and all of the
outstanding patches weren't accepted until 3.7-rc. So I'd say 3.6 would
be your best bet until 3.7 is released. Did you attempt a backport of
the isci driver or using something like an LSI port on 2.6.27? Have you
verified the issue on a more recent kernel?
We're using a driver provided by the hardware vendor. It appears to be
a backport of version 1.0.1 of the isci driver. We've been using it
since mid-March or so.
This is an embedded system, so as is all too common in that environment
upgrading the whole kernel isn't an option since it requires support
from multiple hardware/software vendors.
Upgrading just the driver might be possible--do you think it's likely as
a cause for these errors? The current driver has a binary firmware file
that it uses--would we keep that with the new driver?
