I have atapicam enabled in my kernel conf file and disabling it does nothing. I still get the following errors when trying to read a dvd : acd0: timeout waiting for ATAPI ready acd0: error issuing ATA PACKET command and if I try to mount a cd/dvd, it crashes the system. With atapicam enabled, I get several loops of this at boot: (da0:ata1:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0 (da0:ata1:0:0:0): CAM Status: SCSI Status Error (da0:ata1:0:0:0): SCSI Status: Check Condition (da0:ata1:0:0:0): NOT READY csi:0,0,bb,0 asc:3a,0 (da0:ata1:0:0:0): Medium not present (da0:ata1:0:0:0): (da0:ata1:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0 (da0:ata1:0:0:0): NOT READY csi:0,0,bb,0 asc:3a,0 (da0:ata1:0:0:0): Medium not present Unretryable error (da0:ata1:0:0:0): error 6 (da0:ata1:0:0:0): Unretryable Error Opened disk da0 -> 6 and still no access to acd0 or it's scsi form. The dvdr is set physically set as master (not CS) and runs alone on it's channel. I tried changing the cable from 80 conductor to 40 conductor (spare parts...) and nothing changed. Also, whether I have atapicam enabled or not, booting takes about 5 minutes because the umass probe is hanging. It will ouput 5 times : (probe0:umass-sim0:0:0:0): Request completed with CAM_REQ_CMP_ERR (probe0:umass-sim0:0:0:0): Retrying Command. With about a minute in between. Ironically, after boot, pluging-in a USB mp3 player works and creates da1 successfully. These two problems were not present in the March_05 snapshot. My wild guess would be that something happened to either pass, da or scbus that my system doesn't like. This happens with both ULE and 4BSD. >How-To-Repeat: Enable atapicam or not, enable umass in kernel. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
