We have a slightly similar problem; we've never seen the in-use lockup you describe, but the SCSI adapter cannot find the drives after a reset, halt, or reboot, only after power is cycled. This did not happen with earlier revisions of the Adaptec firmware. Is it possible that a power cycle would get your system back up, without wiggling any wires? This is also under 2.2.1-RELEASE, off the WC CDROM.
