If you send me a revised patch I will commit it. I'm seeing similar stuff on the hpt27xx driver: (probe18:hpt27xx0:0:18:0): INQUIRY. CDB: 12 0 0 0 24 0 (probe18:hpt27xx0:0:18:0): CAM status: Invalid Target ID (probe18:hpt27xx0:0:18:0): Error 22, Unretryable error Should I make a similar change in sys/dev/hpt27xx/osm_bsd.c? Looks like there are two CAM_TID_INVALID lines, but from reading the comments, only the second one should change... Correct? If so, I'll try making the change and make sure everything works well.
