--- Comment #17 from Marek Olšák maraeo@gmail.com --- (In reply to comment #16)
My most stable test case is unfortunately the Mathematica welcome screen. After some 5 mins of work in Chrome followed by a couple of Mathematica restarts, like 5-10, the lockup or segfault happens. Geeqie didn't do anything for me.
I haven't made any good progress with bisecting other than reconfirming that
http://cgit.freedesktop.org/mesa/mesa/commit/ ?id=cb4ad1368551b64756c7b6e2007588e34739b188
fixes a segfault. This fix uncovers the lockup behavior.
The commit fixes code which isn't used by radeonsi. I guess the bisection went wrong.
Maybe apitrace is a way forward to generate something more testable.
Marek: Can you provide more information on the other known problem?
Kernel 3.15-rc1 and later locks up randomly. There is a memory corruption when page tables are moved.
