k3b (Ubuntu)

Bug Description

Binary package hint: k3b

I wanted to write a dvd at 16x, no multisession, verify data after write.
I managed to write one, it got verified, all went ok.
Then I wanted to write a second dvd using the same setup.
5 minutes after the write started, k3b crashed (and some other
open applications went down with it).
The system froze. I could still move the mouse, but couldn't open any
But the dvd kept spinning, as if it were still written.
I left it about 10 minutes or so, with no change (disk still spinning).
I rebooted the system using Alt + SysRq + R, S, E, I, U, B.
But the dvd was still spinning ... I had to shutdown in order to make
it stop.

I have an LG dvd writer.
Os is Kubuntu Feisty on 32 bits, it's an upgrade from edgy.

I tried to write another dvd after this, changing some options, but it
kept freezing.

Thanks for taking the time to report this bug.
Can you also tell us the version of K3B you are having this problem with?

Linker (del-kaos) wrote :

k3b is version 1.0.
I had some other apps open while burning: amarok, firefox, maybe even adept.

This is definitely still a problem. System freezes, Crtl + Alt + Bksp to kill X session but system is unstable until reboot. I have tried under Gnome and KDE desktops (Ubuntu 7.04 installed then kde-desktop packages installed) and system freezes under both desktops after displaying the colourful splash screen. Splash screen stays on top of any other apps launched.

Kernel Version - 2.6.20-15-generic
K3B Version - 1.0-0ubuntu2

I can confirm a reproducible lockup related to K3B 1.0 on my Edgy system. I also happen to have an LG burner and am running gnome. In my case, immediately following successfully burning a DVD (with the write successful message displayed) the system locks (completely unresponsive; ctrl+alt+F1 will not bring up terminal). Any advice regarding what logs I should post (any particular section of DMESG output, etc)?

***Typo in previous post:

This problem did not exist when running 6.10/Edgy on this machine and has only appeared after an upgrade to Ubuntu 7.04/Feisty.

K3b doesnt write DVD s and causes system freeze... Its on a freshly installed Fiesty from edgy..

It appears to be a problem with the k3b launcher splash screen.

I installed AcetoneISO, after reading a review in Linux Format 92. One of AcetoneISO's options is "Burn CD/DVD", clicking on this launched k3b, but without displaying the splash screen and straight into the regular k3b window. I have only tried burning CD ISOs this way (successful), not DVDs yet.

Thanks mate.

I did not try it in gutsy yet.

I also have a DG965WH motherboard (and a Pioneer DVR-111D, firmware 1.29). It uses the Intel g965 chipset, which doesn't include any IDE ports. The board has a Marvell IDE controller chip, which is driven by the pata_marvell kernel module. This is a relatively new driver in the kernel, and I think not totally bug-free yet. e.g. running AMD64 Feisty with the stock kernel, my system would lock up if k3b was running while I closed the tray with a blank dvd-r (or was it +r) in it.

 I'm currently running Gutsy's kernel (and the latest git versions of DRM and mesa for better g965 support; I made a script to download and hack linux-headers...-generic so they don't depend on gutsy's libc, because the headers themselves don't. I guess some of the shipped progs in /usr/src/.../scripts do. BTW, Gutsy's xorg isn't a big improvement for opengl performance or stability if you were using Feisty with mesa from git. They still haven't fixed the tearing (no vsync). I think Feisty's mesa still crashed sometimes on g965, though, and gutsy's mesa is newer and better.)

 Anyway, I can burn DVDs all day without any problems, and the crash while k3b recognized a freshly inserted disc doesn't happen anymore. (I used to have to quit k3b, load a disc, and run it again.)

 So some people's lockups might be the fault of their PATA driver. Try a newer kernel if you have a motherboard with an Intel 965 chipset and a funky PATA controller. BTW, SATA burners are not much more expensive these days, if you're in the market for a new one anyway.

 Usually system lockups are not directly k3b's fault. Locking up the whole system requires messing with hardware (usually), so it's more often a driver or the X server or something else that directly controls hardware that needs to be fixed. Or other software can avoid doing whatever makes the driver cause a lockup.
