Of course, you don't get told this. It just crashes due to bug 132479. In gnome 2.6 you could force a blanking with a checkbox, but that has been disabled. Could you attach the output of list_cddrives on this machine? This is not related to cddrive detection. It seems the drive doesn't handle the media detection mmc commands or something like that. So, all types become unknown. This isn't a huge problem in some cases. I've fixed the g_assert_not_reached() descrived in bug 132479, so things will still work even when the type is CD_MEDIA_TYPE_UNKNOWN. However, this totally breaks the auto-blanking feature, so there is really no way to blank a cd. list_cddrives also uses the MMC commands and shows the type of media in each drive. The ouput of that command (probably with the debug uncommented in the dvd_plus_rw_utils.cpp), and possibly with and without a blank CD in the drive would greatly help. I get it. You don't believe me. Here is the output, with some debug output uncommented and some added: Without media: open /dev/hdc -> fd 3 GET CONFIGURATION failed with SK=5h/ASC=20h/ASCQ=00h mmc_profile: 0xffffffff -1 opened: 1 name: PLEXTOR CD-R PX-W8432T device: /dev/hdc max_speed_read: 32 type: CD Recorder/CD Drive media type: Couldn't open media GET CONFIGURATION failed with SK=5h/ASC=20h/ASCQ=00h media size: -0.00 megs CD-Recorder/SCSI devices only: max_speed_write: 32 id: /dev/hdc With a non-blank cd-rw: open /dev/hdc -> fd 3 GET CONFIGURATION failed with SK=5h/ASC=20h/ASCQ=00h mmc_profile: 0xffffffff -1 opened: 0 name: PLEXTOR CD-R PX-W8432T device: /dev/hdc max_speed_read: 32 type: CD Recorder/CD Drive media type: Unknown Media GET CONFIGURATION failed with SK=5h/ASC=20h/ASCQ=00h media size: -0.00 megs CD-Recorder/SCSI devices only: max_speed_write: 32 id: /dev/hdc I get the same for a CDROM. I should not that the "without media" case was with the door open. If its closed i get the same as with any media. 2.8.1-1 has a patch that makes the crashes go away, but we're still unable to blank if the GET CONFIGURATION request fails, since we don't know whether blanking is required for the media type. 2.8.1-2 fixes the blanking for the non-hal case and is prepared for the hal changes needed to make it work. I'm assigning this to hal, since hal needs to apply the patch i sent to the hal-list for this to work. Created attachment 103948 [details]
This is the patch needed.
This patch is in hal-0.2.98-4. Thanks. |
