    Subject2.6.11-rc[1,2]-mmX scsi cdrom problem, 2.6.10-mm2 ok
    Date
    I'm seeing a problem with latest mm releases; with 2.6.11-rc1,2-mmX every time 
    I fire up k3b, it get stuck here: (last line, previous lines just for
    documentation :) )

    open("/dev/hdc", O_RDONLY|O_NONBLOCK) = 11
    ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
    close(11) = 0
    open("/dev/hdc", O_RDONLY|O_NONBLOCK) = 11
    ioctl(11, CDROM_SEND_PACKET, 0xbfffc590) = -1 EIO (Input/output error)
    close(11) = 0
    open("/dev/hdc", O_RDONLY|O_NONBLOCK) = 11
    ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
    ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
    close(11) = 0
    open("/dev/hdc", O_RDONLY|O_NONBLOCK) = 11
    ioctl(11, CDROM_GET_CAPABILITY or SNDRV_SEQ_IOCTL_UNSUBSCRIBE_PORT,
    0x7fffffff) = 3735535
    close(11) = 0
    lstat64("/dev", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=30220, ...}) = 0
    lstat64("/dev/sr1", {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
    open("/dev/sr1", O_RDONLY|O_NONBLOCK) = 11
    fstat64(11, {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
    ioctl(11, CDROM_SEND_PACKET, 0xbfffd740) = 0
    close(11) = 0
    open("/dev/sr1", O_RDONLY|O_NONBLOCK) = 11
    fstat64(11, {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
    ioctl(11, CDROMAUDIOBUFSIZ or SCSI_IOCTL_GET_IDLUN, 0xbfffd7e8) = 0
    ioctl(11, SCSI_IOCTL_GET_BUS_NUMBER, 0xbfffd8a4) = 0
    close(11) = 0
    open("/dev/sr1", O_RDONLY|O_NONBLOCK) = 11
    ioctl(11, CDROM_SEND_PACKET, 0xbfffd7d0) = 0
    ioctl(11, CDROM_SEND_PACKET

    At this point k3b is stuck in D stat, needs reboot.

    I've thinked of faulty HW, but 2.6.10-mm2 can complete the scan (I haven't
    tried to use that device, to ber honest, after successful initialization).

    On scsi- bus I've the following devices:
    cova@kefk ~ $ cat /proc/scsi/scsi
    Attached devices:
    Host: scsi0 Channel: 00 Id: 02 Lun: 00
    Vendor: Nikon Model: COOLSCANIII Rev: 1.31
    Type: Scanner ANSI SCSI revision: 02
    Host: scsi0 Channel: 00 Id: 03 Lun: 00
    Vendor: PLEXTOR Model: CD-ROM PX-40TS Rev: 1.01
    Type: CD-ROM ANSI SCSI revision: 02
    Host: scsi0 Channel: 00 Id: 05 Lun: 00

    Vendor: ATA Model: Maxtor 6Y160M0 Rev: YAR5
    Type: Direct-Access ANSI SCSI revision: 05

    cova@kefk ~ $ cat /proc/scsi/aic7xxx/0
    Adaptec AIC7xxx driver version: 6.2.36

    Let me know if further details/testing are needed.
