<p dir="ltr">I&#39;m sorry for causing confusion. It crashes for me as well, just not as soon as I start Firefox. Replication of crashes is not consistent. </p>

        <pre>For me it does! I&#39;m on 4.5.6-200.fc23.x86_64 now and the machine still hangs
for some seconds every couple of minutes when I re-activate RC6.

Error message in dmesg is:
