Tyan S5510, with Intel Xeon CPU E31225 @ 3.10GHz
Upgraded to BIOS 1.05a and iKVM 3.00

1 x LSI SAS9201–16i
1 x LSI SAS92118–8i
1 x Intel X520-DA2 dual 10G NIC
although the 10G link wasn't being used for the most recent tests.

Will have to check, I think it may be this one:

The drives are 24 x ST3000DM001 (I was hoping to get low-power Hitachi
drives but they weren't available at the time)

Much appreciated.
However, last night I rebooted one box (the one which wouldn't let me ssh
in) then upgraded it to ubuntu 12.04. It has been running a couple of
concurrent bonnie++ instances for over 24 hours without a hitch.
So maybe it's the mpt2sas driver which is the difference:
[dmesg from Ubuntu 11.10]
mpt2sas version 08.100.00.02
[dmesg from Ubuntu 12.04]
mpt2sas version 10.100.00.00
Regards,
Brian.
