Greetings, I am still seeing the same problems trying to stop audio CDs in my SCSI CD-ROM drive. I am now running a 3.0 kernel from about 6:30AM CST. The machine is a dual Pentium machine, with a Buslogic BT-946c SCSI controller, one 1GB HP SCSI-2 disk, and a Sony 4x SCSI CD-ROM attached. It also has an IDE disk in it. Here is dmesg info for the controller, disk, and cd-rom: bt0: <Buslogic Multi-Master SCSI Host Adapter> rev 0x00 int a irq 16 on pci0.20.0 bt0: BT-946C FW Rev. 4.25J Narrow SCSI Host Adapter, SCSI ID 7, 100 CCBs da0 at bt0 bus 0 target 0 lun 0 da0: <HP C2247-300 0BA4> Fixed Direct Access SCSI2 device da0: 10.0MB/s transfers (10.0MHz, offset 8), Tagged Queueing Enabled da0: 1003MB (2054864 512 byte sectors: 64H 32S/T 1003C) cd0 at bt0 bus 0 target 4 lun 0 cd0: <SONY CD-ROM CDU-76S 1.1c> Removable CD-ROM SCSI2 device cd0: 5.0MB/s transfers (5.0MHz, offset 15) cd0: cd present [316932 x 2048 byte records] I have now verified the problem persists with cdcontrol and cdplay from the ports collection. What happens is, when the drive is issued a stop command from one of those programs, the program hangs in cbwait. Looking into the cdcontrol code, when stop is issued, a CDIOCSTOP is sent to the drive. Is that correct? Also, cdplay managed to get this out through syslog, which cdcontrol had never previously done: (cd0:bt0:0:4:0): PLAY AUDIO MSF. CDB: 47 0 0 0 0 0 42 f 19 0 (cd0:bt0:0:4:0): ILLEGAL REQUEST asc:24,0 (cd0:bt0:0:4:0): Invalid field in CDB I tried issuing some camcontrol commands to the drive, but they all return the above illegal request. I never had these problems with rev 1.7 of /sys/cam/scsi/scsi_cd.c. Is there anything else I can do to debug this problem? -- Kyle Mestery StorageTek's Storage Networking Group To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
