I actually tried with 2 different drives. I can get more detailed, now. The drive lockup and dmesg spamming till the system has shut down as I reported it only occurs if I try to use the drives through the cam interface /dev/cd0 or /dev/cd1. The error message being the same. Here is the dmesg boot output concerning the drives: atapci0: <Intel ICH2 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x37...skipping... acd0: DVDROM <HL-DT-STDVD-ROM GDR8164B/0L06> at ata1-master UDMA33 acd1: DVDR <HP DVD Writer 840b/FF66> at ata1-slave UDMA33 acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 cd0 at ata1 bus 0 target 0 lun 0 cd0: <HL-DT-ST DVD-ROM GDR8164B 0L06> Removable CD-ROM SCSI-0 device cd0: 33.000MB/s transfers cd0: cd present [3799193 x 2048 byte records] cd1 at ata1 bus 0 target 1 lun 0 cd1: <HP DVD Writer 840b FF66> Removable CD-ROM SCSI-0 device cd1: 33.000MB/s transfers cd1: cd present [3793882 x 2048 byte records] If I use the acd0 device mplayer just fails because of failed CSS-key cracking. The dmesg gets a couple of lines with: ata1: FAILURE - non aligned DMA transfer attempted acd0: setting up DMA failed acd0: FAILURE - REPORT_KEY ILLEGAL REQUEST asc=0x6f ascq=0x04 If I use the acd1 device there are no dmesg reports and the dvd plays, but very poorly, as if the drive was in PIO mode. I checked my BIOS settings and all the usual suspects like block-reading, DMA and so on are turned on. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
