maybe the problem comes from your display dogging the HPD signal.

Try adding
"vc4.force_hotplug=1" if using HDMI0
"vc4.force_hotplug=2" if using HDMI1
"vc4.force_hotplug=3" if using HDMI 0 and 1
to cmdline.txt (on existing line) to stop the kernel from 'seeing' hot plug detect signal
I guess that was it.
Been running fine without crashes with that change for more than a week already :)

Thank you :)
