I could obtain the requested dump :) I hope it helps.

Some words are in order: After I knew that the guilty process was /usr/bin/X
and a knew its PID I also tried to get a "gcore <PID>" or to attach gdb to it.
Both failed. Otherwise I also had provided you a backtrace of all threads as I
compiled all packages with "-g -ggdb". (I am a gentoo user.) The process is
stuck in state "D". "kill -KILL <PID>" did not work either.

A second note (I know it is selfish, because you do a great job, and
off-topic.). I bought this new graphics card, because I was being pestered by
with an Nvidia graphics card, a buggy nouveau driver and a lot of crashes due
to an unstable OpenGL. (I know it Nvidia is to blame for the situation not the
maintainers of nouveau.) After 18 month of hope that the situation might
improve, I finally decided to spend money for a new graphics card by AMD. I
thought I would eventually get working PC. Now, it seems I stepped "out of the
frying pan into the fire". Just now I have still the chance to withdraw from my
investment and give the AMD graphics card back to the dealer. Should I do that?
Or may I hope for a fix soon?
