Yes, your patch fixing original problem. Maybe this is candidate for stable releases. Patch tested on 3.14 and system working fine after rmmoding radeon module, no crash after calling: find /sys
But now there is another new kernel crash. When I modprobe radeon module again (after previous successful rmmod), kernel crash. See syslog output in attachment.
