I'm not sure how best to test this but on an imx8mm-venice-gw7902 which has USB, but no display. I find that if DRM_ETNAVIV is enabled I hang at 'etnaviv etnaviv: bound 38000000.gpu (ops 0xffff800010964748)'. If DRM_ETNAVIV is not enabled: - boots fine - usb works - soft reboot works (does not hang) Best regards, Tim
