Maybe you need to change: int err, i = MAX_LANE_NUM, attempt_counter = 0; u32 status; err_retry_init: to int err, i, attempt_counter = 0; u32 status; err_retry_init: i = MAX_LANE_NUM; ? Or just change the "while"s into for loops.

My rootfs is on the sdcard, I've taken the card out, booted an old laptop on https://www.system-rescue.org/ and using an SD card reader copied /boot and /lib/modules from a known-working Armbian image to the card. Boot, then apt update/apt upgrade to get the fixed kernel. I've also started backing up the current kernel every time I run an upgrade 🙂

I can confirm that the latest Armbian kernel (6.0.6) boots just fine on rockpi 4a (and 6.0.5 did not).
