Bug#998718: Brasero fails (on Testing) burning an ISO image on a CD-RW

[Thomas Schmitt]

Hi,

i am upstream programmer of libburn, which might be in charge of
burning underneath Brasero. Regrettably i cannot interpret Brasero's
messages unless they come from libburn or libisofs. So i am not sure
whether i can help with fixing Brasero.

The statement by other software that no medium is found in /dev/sr0
surprises me. Such a status assessment is usually done by the drive
and i am not aware of any regular means to let a drive ignore or deny
its loaded medium.

Do you see anything in dmesg that occured when Brasero failed and looks
related to "sr" or "cdrom" ?

Can i talk you into inquring the drive by xorriso and logging its
SCSI transactions when the drive has gone mad from Brasero and a medium
is still inserted ?

  xorriso -scsi_log on -outdev /dev/sr0 -toc 2>&1 | tee -i /tmp/xorriso.log

This would give insight into what the drive tells about its status
without the programs-in-the-middle. The log is quite verbose and will
have several hundred lines. Please post /tmp/xorriso.log as attachment
or send it to me by private mail.

(I wonder why udevadm monitor of Testing is so eager to insert blanks
everywhere. But that would be a different bug, if it is not a copy+paste
artefact.)


Have a nice day :)

Thomas
