 I can confirm that the suggested fix was a red herring. We experience
 the same crashes here, tried tweaking everything, the best we could do
 was delaying the crash a little bit. This also happens with the aacu
 drivers provided directly by adaptec (they're incredibly slow, which
 basically helps delaying the crash by 1-2 hours). I would assume this is
 some problem with the controller/firmware (the firmware version shipped
 is newer than the BSD driver version provided by adaptec).
 
 Yuri Gorchakov just fowarded me this piece of information - adaptec just
 released a new firmware for this controller:
 
 "Hello Yuri,
 Hello from Adaptec,
 This message is in response to the problems that you are experiencing
 when using the Adaptec 5405 in your FreeBSD system.
 Adaptec recently posted a firmware upgrade for the Adaptec 5405 and the
 release notes doe mention a couple of fixes for FreeBSD.  You may want
 to try this to see if this might help to resolve your issues.
 The most recent firmware download is available at the link below.
 http://www.adaptec.com/en-US/speed/raid/asr/fw_bios/5405_fw_b17380_exe.htm
 Adaptec Technical Support"
 
 Maybe this helps you (even so the release notes don't look that
 promising and the number of severe problems fixed makes me wonder if I
 ever want to use adaptec again :).
 
 Michael
