amd_fix.sh

I've been having a problem with display corruption on Fedora using recent
updates. Here is my report on their bug tracker:

https://bugzilla.redhat.com/show_bug.cgi?id=1745380

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.
