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.

Regards.
