Hi Michel,
[..]
The most striking problem of kernel 3.18.9-rt4 affects all systems that
are equipped with Radeon graphics (irrespective whether PCIe cards or
APUs with on-chip graphics). They suffer from a hanging radeon driver.
The block occurs when accelerated graphics load is created by x11perf or
gltestperf. Sometimes only the graphics are frozen while ssh login still
is possible, somtimes the entire box is no longer accessible at all. In
any case, a reboot is needed to recover from this situation.
Here is a selection of kernel messages:
[...]

might help for this.
Thanks a lot. I have applied these patches to a number of systems:

The graphic boards still crash and freeze the screen, but in contrast
to the earlier situation the systems remain accessible, and the X
Window server can be restarted after the offensive programs are
removed. The crashes were reliably triggered by
- gltestperf
or
- x11perf -repeat 3 -subs 25 -time 2 -rect10
but the crashes also occur several times per day during normal work
such as browsing the Internet or writing a text document. If you wish
me to provide additional diagnostic information such as running test
programs while the graphic boards are unresponsive, I certainly can do
that.
Below are the related kernel messages.
Thanks,
-Carsten.
