I see similar messages on the bootup of my 2.1.109 box, but it proceeds to
work just fine.

(scsi1:0:-1:-1) Scanning channel for devices.
(scsi0:-1:-1:-1) Bad scbptr 255 during SELTO.
(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
SCSISEQ = 0x12 SEQADDR = 0x9 SSTAT0 = 0x10 SSTAT1 = 0x8a

I've found that messing around with the BIOS settings dealing with
resetting the card at boot time can change this. Perhaps the card is
being initialized to a configuration by BIOS that the driver doesn't
completely clear, hence the scbptr error? 255 certainly seems like an
initialization value...
