But it seems like this is happening only in amd64 builds. After being unable to find a solution for the problem I installed Debian stable x86, and the problem is gone.

Using the same apps, and the same versions of libgl1-mesa-dri and xserver-xorg-video-radeon? (GPU lockups are usually caused by userspace bugs)

If so, it would be interesting to see dmesg for both cases from the same kernel version.
