Log file
I have a reproducible crash in the radeon driver when using kdenlive and
scrolling the project timeline). Driver version is the git code from 2010/12/15
(yesterday) but was also present in the pull I did on Oct 29.
Attached is my Xorg.log - looking at the offsets the crash was in
EVERGREENComposite at the line
vbo[0] = (float)dstX;
with a null pointer dereference - which pretty well must have resulted from
radeon_vbo_space returning NULL.
If I disable EXA and use XAA instead it crashed in EVERGREENSolid, again when
dereferencing the return value from radeon_vbo_space
This has been reported a couple of times eg
https://bugs.freedesktop.org/show_bug.cgi?id=30945 and on the mailing list. I
have slightly different hardware (an Asus EHA5450) so this does look like a
real problem with the Evergreen code.
Other factors
Hardware: Core i7 920
OS: Fedora 14 (x86_64)
Kernel: 2.6.36
