I am using an app which is using the vc4-drivers. Sometimes videos freeze for an instant, and I see a kernel message saying :
[drm] Resetting GPU
After that, some font are no more displayed but the app still runs. I have tried to disable those drivers in /boot/config.txt, but I need them... I have although tried to improve gpu_mem from 256 to 512, but it does not help...
Any idea ? Thank you !
