Hello, I have patched linux-2.5.70-bk12 with the packet-2.5.70 patch and rebuilt the kernel. I was trying to format a disk, and I got the following error: bear:~# cdrwtool -d /dev/sr0 -q using device /dev/sr0 2338KB internal buffer setting write speed to 12x Settings for /dev/sr0: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/sr0. The disc is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now. ENTER to continue. Initiating quick disc blank Disc capacity is 276160 blocks (552320KB/539MB) Formatting track wait_cmd: No such device Command failed: 04 17 00 00 00 00 00 00 00 00 00 00 - sense 00.f1.41 format disc: Illegal seek I am using a Plextor 12x SCSI CD-RW. The kernel log contains the following: sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray Attached scsi CD-ROM sr0 at scsi0, channel 0, id 4, lun 0 cdrom: This disc doesn't have any tracks I recognize! advansys: advansys_reset: board 0: SCSI bus reset started... advansys: advansys_reset: board 0: SCSI bus reset successful. scsi: Device offlined - not ready after error recovery: host 0 channel 0 id 4 lun 0 sr0: CDROM not ready yet.
