Created attachment 285359 [details] Full dmesg on 5.2.13 Once in a while immediately after resuming from suspend the screen freezes for a moment and then I lose all video signals. System is able to be rebooted with sysrq. Hardware: * Radeon RX 470 * Ryzen 2700 * 64GB ECC RAM No significant load is put on the GPU, because the system is only used for work, browsing and playing video. You can also see bug 202891 (__nvme_disable_io_queues triggers WARNING in kernel/irq/chip.c:210) in both logs, but that one happens far more often without this bug comanifesting.

Seems again a duplicate of this https://bugzilla.kernel.org/show_bug.cgi?id=204965 - update to latest kernel from here https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next and try again.
Patches are in 5.4 as well.
