Here is my report on their bug tracker: <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1745380">https://bugzilla.redhat.com/show_bug.cgi?id=1745380</a> I can confirm that when compiz is enabled, the system will lock up when it's started. Adding "iommu=pt" to the kernel flags in grub2 will allow the system to boot without freezing but the display is still corrupt. Adding "AMD_DEBUG=nodcc" to the environment provides a complete workaround (without the need for the kernel flag). I've attached a file "amd_fix.sh" which if placed in /etc/profile.d/ will provide a workaround until this can be fixed in the kernel or wherever the problem is.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
