Unfortunately, radeon_drv.so was compiled without debug symbols.
There are also the following messages in the system log right from the crash
time:
kernel: [TTM] Unable to allocate page
kernel: error: [drm:pid42432:radeon_gem_object_create] *ERROR* Failed to
allocate GEM object (254115840, 2, 4096, -12)
