Created attachment 141478 = [details] kernel panic This is a follow-up from bug https://bugs.freedesktop.org/show_bug.= cgi?id=3D105018. If I leave my laptop in its dock (one HDMI and one DisplayPort) it has a high chance of kernel panicking when DPMS turns the displays off. This affects my Dell Precision = 7720 with a Radeon Pro WX 7100 on Archlinux, kernel 4.18.5. My boot parameters include amdgpu.dc=3D1 (a redundant option nowadays, I know, I forgot to rem= ove this option). Suspend/resume work are fine, this happens only immediately a= fter idle blanking. As far as I can tell this does not occur when using only the laptop screen but I could be wrong as I spend the majority of my time on the dock. I've attached a kernel log. For now I work around the issue by disabling dp= ms entirely. Thank you!
I should also note that a very similar software (desktop) setu= p with a Vega 64 card has no such issue with an external displayport monitor.
