backtrace

Hi guys,

If I have commit 'gallium/radeon: just get num_tile_pipes from the winsys',
everything I try to run gives me
/var/tmp/portage/media-libs/mesa-9999/work/mesa-9999/src/gallium/drivers/radeon/r600_texture.c:562:
r600_texture_get_htile_size: Assertion `0' failed.


I've attached a gdb backtrace of the assert. I'm on a HD 7950 TAHITI.

Let me know if you need anything,

sarnex

There is a backtrace but no result of any bisect...?
