radeonkms blank screen with FreeBSD 13.3 and RV730 GPU #293

Open andrewhotlab opened 3 months ago

andrewhotlab commented 3 months ago

After upgrading FreeBSD from 13.2 to 13.3, the screen goes blank when radeonkms module loads. Running on iMac10,1 with Radeon RV730 GPU.

DRM KMOD version

drm-510-kmod 5.10.163_8
drm-kmod 20220907_1

To Reproduce Load radeonkms.ko on FreeBSD 13.3-RELEASE with a Radeon RV730 GPU.

Additional context I obviously rebuilt all DRM related Ports, graphics/gpu-firmware-kmod and x11-drivers/xf86-video-ati. Thanks to Boot Environments, I tried the same steps with FreeBSD 14.0 (which brings graphics/drm-515-kmod), and the screen freezes when loading radeonkms.ko. The system is reachable via SSH with both releases. No problem with FreeBSD 13.2

I'm not very experienced with this type of issue... there is a way to make the module logging debug info when it loads?

I've found some additional info in /var/log/messages... here are the relevant lines from FreeBSD 13.3:

andrewhotlab commented 2 months ago

Still not being able to solve the issue in FreeBSD 13.3, but in the mean time I realized that screen freezing at radeonkms.ko load in FreeBSD 14.0 was due to my mistake: I missed to rebuild all the DRM-related Ports after upgrade to that latest OS major release.

Any suggestion to help me troubleshooting the issue on FreeBSD 13.3 will be well accepted! :)
