FYI I have now tracked down the cause of the regression, which is outside BusLogic code; specifically commit af73623f5f10 ("[SCSI] sd: Reduce buffer size for vpd request"). It wasn't exactly easy as for an odd reason Linux versions ~3.15 through to ~4.5 usually crash with this system in early startup before anything is output to the serial console. I'm still working on a proper fix, but with said commit reverted the system boots and with your series applied it has survived system-wide fsck even, which happened to get scheduled.
