[Bug 110484] Re: k3b causes system freeze

[Peter Cordes]

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.
