[ltp] Re: x.org 7.0 + radeon + mergedfb = crashes?

[Michael]

Well, the original poster did not bother to add his report to the xorg
bugtracker. But as this seems to be something not limited to only one
machine, maybe other that experience the same problems might add to the bug
report, so here is the link:

https://bugs.freedesktop.org/show_bug.cgi?id=7154

Cheers,

Michael
