Yes, they have been quite a bit more forthcoming with information than
in the past. I've even received information from the engineering department
about bug errata that isn't published anywhere else.

All of the information is available including a driver that is very
stable under FreeBSD:

changing root device to da0s2a
The largest factor affecting the Linux driver is the brain damage
in the Linux SCSI layer. You can't blame the current situation on
Adaptec.
