Panic in amdgpu_get_vblank_counter_kms when resuming monitors from standby

[franrogers]

Describe the bug drm-kmod mostly works fine for me, but when I'm away from the computer, come back and move the mouse to wake up the monitors, frequently the machine will either immediately reboot, or scroll kernel panic messages endlessly until I hard reboot the system.

FreeBSD version FreeBSD 13.1-RELEASE-p2 GENERIC amd64

DRM KMOD version drm-510-kmod 5.10.113_7

To Reproduce Steps to reproduce the behavior:

1. Let xorg sit idle so the displays go to sleep.
2. Come back and see if it reboots or spews panic output on the console in an infinite loop.

I also have this issue sometimes after waking up from suspend to ram.

It happen after updating drm-510-kmod from 5.10.113_1 to 5.10.113_6.

@evadot Do you have any ideas why?

[evadot]

Is this still happening with 515 or 61 ?
