So the firmware does indeed wedge under high load. Given the issues I've had so
far with LSI SATL I'm not surprised.
Does the same thing happen when running on a single disk, ie without MD?

Hello .
I used to have the same issues with MD . yes .
I'm using BTRFS , I don't know if BTRFS RAID code was ported from MD , but the
issue is the same .
I didn't try anything other than BTRFS and MD .

A race condition may happen if two threads are both trying to open the same sg
with O_EXCL simultaneously. It's possible that they both find fsds list is
empty and get_exclude(sdp) returns 0, then they both call set_exclude() and
break out from wait_event_interruptible and resume open.
Now use
Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock.
