Or a GUI > desktop component that is started after login into xdm? Neither those are it. Was logging in via console and disabled mythbackend. tried the code, However they only tell about the dvd drives themselves and I suspect it has more to do with the changer side of the device. I get 3 /dev/sg? a /dev/sch0, a couple nodes in /dev/bsg/, a /dev/fw1 , and the 2 dvd drive nodes. I'm kinda sure it is udev but am not sure where to patch to do similar to the below patch for the others. In other testing, when I tried booting with init as /bin/sh and loaded the modules manually the device loads fine and no errors. However once I start init and get a login it has disabled errors on parts. > I don't know if there is a logging facility in the kernel's SCSI layer > that could expose the process name of SCSI ioctl issuers, but you can add > one: > > --- a/drivers/scsi/sr.c > +++ b/drivers/scsi/sr.c > @@ -479,6 +479,9 @@ static int sr_block_open(struct block_de > ret = cdrom_open(&cd->cdi, bdev, mode); > if (ret) > scsi_cd_put(cd); > + else > + printk(KERN_INFO "***** %s opened by %s *****\n", > + cd->cdi.name, current->comm); > } > mutex_unlock(&sr_mutex); > return ret; > > -- > Stefan Richter > -=====-==-== -=-= ===== > http://arcgraph.de/sr/ > dmesg log after C200 poweron [48028.951220] firewire_core: phy config: card 0, new root=ffc1, gap_count=5 [48029.549845] firewire_core: created device fw1: GUID 003060f200002759, S400 [48029.609450] scsi8 : SBP-2 IEEE-1394 [48029.810579] firewire_sbp2: fw1.0: logged in to LUN 0000 (0 retries) [48029.812794] scsi 8:0:0:0: CD-ROM TOSHIBA DVD-ROM SD-M1212 1032 PQ: 0 ANSI: 0 CCS [48029.817707] sr1: scsi3-mmc drive: 32x/32x cd/rw xa/form2 cdda tray [48029.817962] sr 8:0:0:0: Attached scsi CD-ROM sr1 [48029.818159] sr 8:0:0:0: Attached scsi generic sg5 type 5 [48029.820363] firewire_sbp2: fw1.0: logged in to LUN 0001 (0 retries) [48029.822509] scsi 8:0:0:1: CD-ROM TOSHIBA DVD-ROM SD-M1212 1032 PQ: 0 ANSI: 0 CCS [48029.827662] sr2: scsi3-mmc drive: 32x/32x cd/rw xa/form2 cdda tray [48029.827907] sr 8:0:0:1: Attached scsi CD-ROM sr2 [48029.828073] sr 8:0:0:1: Attached scsi generic sg6 type 5 [48029.830277] firewire_sbp2: fw1.0: logged in to LUN 0002 (0 retries) [48029.835850] scsi 8:0:0:2: Medium Changer Escient Powerfile C200 04A PQ: 0 ANSI: 3 [48060.704057] firewire_sbp2: fw1.0: sbp2_scsi_abort [48070.704061] firewire_sbp2: fw1.0: sbp2_scsi_abort [48070.704292] sr 8:0:0:1: Device offlined - not ready after error recovery [48070.704387] sr 8:0:0:1: rejecting I/O to offline device [48071.031118] ch0: type #1 (mt): 0x0+1 [medium transport] [48071.031126] ch0: type #2 (st): 0x4+200 [storage] [48071.031132] ch0: type #3 (ie): 0x1+1 [import/export] [48071.031136] ch0: type #4 (dt): 0x2+2 [data transfer] [48071.364376] ch0: dt 0x2: READ ELEMENT STATUS failed [48101.728068] firewire_sbp2: fw1.0: sbp2_scsi_abort [48111.728057] firewire_sbp2: fw1.0: sbp2_scsi_abort [48111.728268] sr 8:0:0:0: Device offlined - not ready after error recovery [48111.728394] sr 8:0:0:0: rejecting I/O to offline device [48111.730902] ***** sr0 opened by udisks-daemon ***** [48111.730980] sr 8:0:0:1: rejecting I/O to offline device [48111.731035] sr 8:0:0:1: rejecting I/O to offline device [48111.731157] sr 8:0:0:1: rejecting I/O to offline device [48111.731167] sr 8:0:0:1: rejecting I/O to offline device [48111.731625] sr 8:0:0:0: rejecting I/O to offline device [48111.731652] sr 8:0:0:0: rejecting I/O to offline device [48111.732300] sr 8:0:0:0: rejecting I/O to offline device [48111.732326] sr 8:0:0:0: rejecting I/O to offline device [48111.734325] ***** sr0 opened by udisks-daemon ***** [48111.757569] sr 8:0:0:1: rejecting I/O to offline device [48111.757590] sr 8:0:0:1: rejecting I/O to offline device [48111.757729] sr 8:0:0:0: rejecting I/O to offline device [48111.757753] sr 8:0:0:0: rejecting I/O to offline device [48111.762602] sr 8:0:0:1: rejecting I/O to offline device [48111.762626] sr 8:0:0:1: rejecting I/O to offline device [48111.762684] sr 8:0:0:1: rejecting I/O to offline device [48111.762694] sr 8:0:0:1: rejecting I/O to offline device [48111.765711] sr 8:0:0:0: rejecting I/O to offline device [48111.765736] sr 8:0:0:0: rejecting I/O to offline device [48111.765796] sr 8:0:0:0: rejecting I/O to offline device [48111.765806] sr 8:0:0:0: rejecting I/O to offline device [48112.062578] ch0: dt 0x3: READ ELEMENT STATUS failed [48112.062586] ch0: INITIALIZE ELEMENT STATUS, may take some time ...
