We are also having some trouble with many "unexpected busfree while 
idle" events under FreeBSD 5.3-RELEASE where the disk is busy with 
database activity.  One model is configured thus:

Bios: Phoenix - Award Bios v6.00PG
Motherboard: Supermicro P4SCA/P4SCE BIOS 1.1C
SCSI: Adaptec SCSI BIOS v4.30.0 29320A Controller
Disk: 1 Seagate ST336607LW 0007 10K-RPM 73GB disk
CPU: P4-2.8 533 FSB
MB:   Single P4 Intel 845GE

Rolling the driver back to 2004-09-01 on the RELENG_5 branch seems to 
have alieviated the problem for us (thanks to Anton Berezin's email of 
2005-01-21).
