There has been a couple of important fixes committed to main trunk
recently.  They address SCSI issues, which affect both of processors
(R3000 and R4000), and both of SCSI implementations (pmax SCSI and MI
SCSI).

The fixes have been pulled up into 1.5 release branch, and next 1.5
snapshot will have them.
