GEOM: create disk da7 dp=0xc4639850 da7 at ahc0 bus 0 target 8 lun 0 da7: <SEAGATE ST318203LC 0002> Fixed Direct Access SCSI-2 device da7: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da7: 17366MB (35566480 512 byte sectors: 255H 63S/T 2213C) (da7:ahc0:0:8:0): Unexpected busfree in Data-out phase SEQADDR == 0x5f (da7:ahc0:0:8:0): WRITE(06). CDB: a 5 bd df 80 0 (da7:ahc0:0:8:0): CAM Status: SCSI Status Error (da7:ahc0:0:8:0): SCSI Status: Check Condition (da7:ahc0:0:8:0): UNIT ATTENTION asc:29,1 (da7:ahc0:0:8:0): Power on occurred field replaceable unit: 1 (da7:ahc0:0:8:0): Retrying Command (per Sense Data) The above error occurs when I try to init the disk when it's plugged into a single SCA80 -> 68pin drive adaptor, this particular drive adaptor has no part number that I can find, but does have 3 IC's on it, no other singel dive adaptor i have ever seen has had these chips. This same drive works fine when plugged into the 5 disk backplane, or plugged in to a different make/model of adaptor (one with no chips) I have 7 of these adaptors and all of them exhibit this same problem with any SCA drive I plug into them. I have test these adaptors under both -CURRENT and -STABLE on adaptec 2940 U2W's. This setup does cause panics under -STABLE at boot, I haven't tested under -CURRENT. I don't happen to have the output of a panic handy if someone needs this let me know and I'll track one down. If any further information is needed please let me know and I'll be happy to provide what ever I can.
