panic on 14-CURRENT; AMD NAVI10; X suspension/resumption; vm_fault_lookup: fault on nodefault entry ...

[thisplacestinksoffascism]

Describe the bug Frequent panics, possibly related to monitor resumption from suspension with multihead system.

I have had very little success with a stable X since 0c38674b389ad385820321af5f8969f73a8eeb4f. The system will frequently and randomly (within 3 days if Cthulhu is having a cat nap) panic, unfortunately (it appears that the DRM prevents the use of the kernel debugger now), the screen will either freeze (at some Xscreensaver demo) or remain off.

I have a core from an unassisted crash dump.

I noticed this if I attempt to wake up X (either asleep from xscreensaver, of if that is disabled, via X DPMS), and there is no response, or the system reboots. If the system does not reboot, it will not accept any SSH sessions, or will drop existing sessions when digital shit hits the fan.
