Two things I think you should consider doing... 1) in your next post (and any bugs you open), include the `uname -a` of the last known to work correctly CentOS/RHEL kernel, and the `uname -a` of the first known to not work correctly CentOS/RHEL kernel and the respective versions of radeon &| flrgx drivers. 2) try out elrepo's el6 kernel-lt & kernel-ml and see if they work correctly for you. I suggest this, because for me it did workaround an issue with intel chips (I guess I need to see what it will take to get the elrepo folks to make just a back-ported intel driver from 3.17 [first known to work again, 3.16 does not]) . http://lists.centos.org/pipermail/centos/2014-November/147579.html Even when this disclaimer is not here: I am not a contracting officer.
