The problem occurs apparently with page 4 and page 8. Sbp2 has a

That's going to cause fun problems on reboot if it actually has write-behind

StorageLynx revision A features the same MODE SENSE bug. This bridge
reports type 14 (TYPE_RBC).
Pardon? If it's type 14, we won't issue MODE SENSE for page 8 and will
go for page 6 instead...
Of course sg does not care for any black list flags (like sd_mod and sr_mod do), but considering the nature of the bugs and anticipated usage of affected devices, there is hardly a reason for further safeguards in sbp2, let alone sg.
Maybe, maybe not. Note that e.g. aforementioned INQUIRY bug in pl3507 is
triggered by dmraid, which works via SG_IO, just as scsiinfo. And unlike
scsiinfo it's run from /etc/rc.sysinit on current FC4...
