Description Lloyd Osten 2021-01-29 14:47:44 CET

Description of problem: K3B freezes after burning an ISO to DVD


Version-Release number of selected component (if applicable): 20.12.0


How reproducible: Seems to happen every time


Steps to Reproduce:

This is the version supplied with Mageia 8. (K3B v20.12.0)

After successfully burning a 3.6G ISO file to DVD, attempting to close K3B (v20.12.0) just totally locked up. I tried clicking the "X" in the top right corner (I use Plastik) but nothing happens at all. I can minimize it, but that's all. ps ax shows a STAT of SLl (I don't know what that is) The only way I can close K3B is to use the Kill PID command. I note that it DID close when burning a data file (not an ISO) to a DVD


STEPS TO REPRODUCE
1. Burn an ISO file to DVD

2.Try closing K3B using the "X" in the top right corner. 
3. 

OBSERVED RESULT K3B froze solid.


EXPECTED RESULT It should have closed. It didn't.

Sorry about this difficulty.
We had another bug about being unable to close an application (k3b ?) window, but I cannot find it.

> This is the version supplied with Mageia 8
Can you please be more precise about the origin of the system you were using. Mageia 8 has passed through various stages, currently RC something. Presumably the system was up-to-date.

Just to give some system information, can you please post the O/P of:
 $ inxi -MSd
and if you can suffer the problem again (because writing a big ISO DVD takes time), post the O/P of:
 $ journalctl -b --no-hostname | grep /dev/sr0
(or whatever the device-id of the drive is).

I recently burned a couple of ISOs to DVD-RW with k3b without this problem; on an internal ATAPI drive, up-to-date Mageia 8/Cauldron.
After just starting k3b, without inserting any medium, I am seeing:
$ ps ax | grep k3b
  60218 ?        SLl    0:04 k3b
  60351 ?        S      0:00 tags.so [kdeinit5] tags local:/run/user/1001/klauncherwBYyNA.1.slave-socket local:/run/user/1001/k3bkbewKm.1.slave-socket
...
  60358 ?        Sl     0:00 thumbnail.so [kdeinit5] thumbnail local:/run/user/1001/klauncherwBYyNA.1.slave-socket local:/run/user/1001/k3bDtjXFJ.8.slave-socket
 so the SLl status looks normal.

I have been using k3b -> Tools -> Burn Image in a Cauldron system updated daily for several months, and I don't see this.

Maybe run it under strace and see what happens when it freezes ?

I replaced my DVD drive with one with updated firmware. This seems to have fixed the problem. The old one had firmware from 2015; the new one has firmware (5 versions later) from 2020.

Thanks for that good feedback.
Closing the bug; you can re-open it if necessary.
