 Dear all,
 
 I've tested new firmware from Adaptec
 (http://www.adaptec.com/en-US/speed/raid/asr/fw_bios/5405_fw_b17380_exe.htm) and was able to
 heavily load the I/O subsystems on the server for 2-3 hours with blogbench at various loads
 and make -j16 buildworld, everything worked smoothly, but at some point the controller locked
 up same way as before.
 The firmware didn't fix the issue, may be prolonged the lock up for little bit.
 
 Yuri.
