It was an oversight.  It seems that this section of code came from the
aic7xxx driver where, depending on controller model, the protocol version
must be reported differently.  I missed some of the duplication when trying
to remove it in my last checkin.  :-( Should be fixed now.

The error only occurs on rev B. controllers (0x10 reported in the PCI
revision register).  The machine not reporting the error has an A4
part.

Invalid command opcode.  CAM will usually report the command that failed.
You don't see any other output?
