I presume the warning is logged because this SCSI command returns sense 
data. If this is the case then this is IMO a kernel or driver bug and 
should be reported to solaris developers. SCSI errors should only be 
logged if the sense data contains real error codes. In this case sense 
data contains the ATA Return Descriptor as requested.

But I have no idea why this does not happen when 5.39 is used as it 
issues the SAME command.

Thanks,
