Hello,

Today, I installed "kernel-desktop-2.6.37.6-24.1.x86_64" from repository "http://download.opensuse.org/repositories/Kernel:/openSUSE-11.4/openSUSE_11.4/".

When burning DVDs with k3b, messages pop up in KDE4's system notification. The following is an excerpt from the system log:

This seems to be related to a bug in the kernel described at 
"http://lkml.org/lkml/2011/4/6/416" and you may have to apply a patch.

NB: The kernel does not crash and the DVDs that have been burned are fine.


Reproducible: Always

Comment 1 Forgotten User Xl7iAZAFUm 2011-05-14 22:35:35 UTC

I face the same bug, but can't say what was the reason and so that patch (proc: fix oops on invalid /proc/<pid>/maps access) is really needed.

#uname -r 
2.6.38.6-26-desktop

I believe that this is a duplicate of bug 693382.
