This describes timeouts during the burn process. Not what
you experience.
I riddle about "faio_wait_on_buffer" in the report about cdrskin.
Neither libburn nor cdrskin have it or use it as system call.
I cannot find it in linux-source-3.16, but rather among the
software of Joerg Schilling (cdrecord et.al.).

This is an aborted SCSI command with an error code probably
fabricated by the kernel.
But the follow-up
looks more similar to your problem.

Regrettably no. Therefore my advise to ask kernel developers
if you can find some and get them interested.
Burn programs are userland tools and rely on flawless
execution of ioctl(SG_IO).

Ewww ... that's really old. And i am not aware that it
ever applied to USB connected drives. I used it a decade
ago for IDE connected drives. /dev/sg rather than /dev/sr.

Finally it is supposed to use the same low level drivers
as the /dev/sr driver. I'd expect that the problem sits
at the low level.

Have a nice day :)
