Each new IO attempt triggers a new set of these messages. The hex number after the COMMAND word is different for each new IO request but of course stays the same for repeated messages relating to the same original IO request aac0: COMMAND 0xc551a7e8 TIMEOUT AFTER 147 SECONDS I have googled on this and similar posts related to 2120S controllers all seemed to have different causes and fixes... I thought that 5.2.1 would have fixed all of this. This isn't good. Any hints or ideas on what is causing this? I can get into the controller at POST time and it checks out... Can you boot the machine at all? If so, could I feed you some patches to help diagnose the problem? Long time ago (humm 3 mounths ;-)) ) I've same problem with a Adaptec 2120S on FreeBSD 5.2 The reconstruction don't work and sometime the machin hang up with same kind of message. I solve the problem (after many time) by to remove the SCSI terminator on the array (where I put the hot-plug disk). Hope this help.

About four years ago, on FreeBSD 4.2 or 4.3, I saw a similar problem. The actual message was a bit different (and I don't recall it exactly), and sometimes the machine continued to run, sometimes not. It turned out that, in the 2U box we were designing, we had the SCSI cable folded and twisted too tightly, and two of the connectors were a few cm. too close. (We had either four or six drives in this box.) We were lucky enough to be able to get one of the FreeBSD SCSI driver's authors to look things over, and after a couple of days with the box he decided that there really was a problem in hardware and taught us about the care and feeding of SCSI cables. Part of the solution was shortening a long run of the cable that forced us to fold it. (The lab prototype was built with an off-the-shelf cable.) Mark Terribile __ Do you Yahoo!? Yahoo!

I hope this is a good place to send this. While the drives and controller are SATA, the driver is the SCSI aac driver for the adaptec raid, hence this group. I would appreciate any attempts to help me understand what is going on. I have flashed the latest BIOS and Firmware into the card and upgraded FBSD to 5.2.1-RELEASE and it still has this problem suddenly. Rebooting, etc have no effect. I would appreciate being directly cc: ed on any replies, as I am subscribed to -questions but not -scsi thanks I rarely read the freebsd-questions@ list, but you are welcome to email me directly with aac driver questions.
