dmesg
On resume after suspend I get the following error on my Dell Latitude E6540
with an Intel and a Radeon graphics controller running Arch Linux:
[30893.254641] [drm:atom_op_jump [radeon]] *ERROR* atombios stuck in loop for
more than 5secs aborting
[30893.254655] [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck

In the attached output of dmesg, you'll see the error between 6170.599551 and
6291.483893 as well as after 30893.254641. The errors with the lower time
happened after resume on a docking station with 2 DVI displays, the errors
starting at 30893.254641 happened after resume back on the previous docking
station with 1 DVI display. While I experience no issue in the first case, in
the latter case Xorg crashes. Xorg keeps crashing on every start and the above
error is printed until reboot.
I've now tried different kernel versions and the error starts with Linux 4.17.
When looking for differences between 4.16 and 4.17 I found this commit:
<a href="https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.17.y&id=07f4f97d7b4bf325d9f558c5b58230387e4e57e0">https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.17.y&id=07f4f97d7b4bf325d9f558c5b58230387e4e57e0</a>
Could this be the reason for the issue?
Let me know if you need any further information.</pre>
