Adaptec 2120S problem

[Joel Adams]

Hi,

I've been running a new server with 4.8-RELEASE-p13 for the past week, and it's
been fine, until this morning where I've had the same SCSI error twice. Once it
comes, the system is basically unusable (you can't ssh in) and needs a hard
boot. An example error:

aac0: COMMAND 0x342622c TIMEOUT AFTER 34 SECONDS

This is the error, and it continually repeated, although the command and timeout
values change. Does anyone have any idea what this means? 

I have not built my kernel with aacp. Latest controller firmware has been
installed. The power supplies seem OK.

Any help would be much appreciated.

Thanks,

-Joel.
