Perhaps, but they were spamed right before the crash and stopped with it.

I will try that.

Right now I started it with R600_DEBUG=nohyperz and I get the output I’ll join.

On stdout side I got a 'radeon: mmap failed, errno: 12' error and on the syslog
side I got a standard segfault message. There was no other message in syslog.
