There is a bug report about this with more information over at freedesktop.org
https://bugs.freedesktop.org/show_bug.cgi?id=110674

It affects 5.1 and 5.2 while 5.0 was fine.

I can confirm this bug, using kernels 5.1 or higher with two DP monitors
connected leaves me unable to boot. Disconnecting one monitor makes it work as
expected.

If i boot with a single monitor and then plug in the second one after booting
the system crashes with graphical corruption.

On older kernels everything works fine.

I have the same monitors as sehellion and can confirm this issue with Radeon
VII is still not fixed in 5.3-rc3.
