And I've also run this workload on another test box here over a week and not
been able to reproduce the problem :-(

Yes, sorry I haven't had time to dig around for the data until now.
The message in question was
and it turns out I had attached a truncated version of dmesg. The full
one is attached here.
Now: I should say it's not too late for us to ditch the LSI controllers, so
perhaps it's time for me to ask a different question.
Does somebody know a good controller card (or cards) which will let us
connect 24 SATA drives into a Linux server in a rock-solid manner? I am
open to solutions which provide RAID on the controller card, and also to
HBAs which require software RAID.
It does need to be SATA because we are looking at getting maximum volumes of
archive data stored at minimum cost, using 3 or 4TB drives. Read/write
performance is not important. However there will be times when we hammer
the array hard, doing bulk imports or reads of data, so the controller needs
to work happily under those conditions.
