New Rock5 - First steps, first problems: random reboots and ubuntu updates not working

#21

AND I had these locks with a 5.10.110 kernel (which also has non-working DVI over HDMI). Now runs on 5.10.160 fine (well, dmesg reports a spin lock crash on boot, but this seems not harm the kernel )

#22

Runnning that version, armbian - 5.10.160-rockchip-rk3588

#23

I added a cooling fan to my passive system. I have seen temps to 55 degrees celcius before and system now runs 32-33 degrees. No restart for 100 hours now, of which 24 hours of stress-test.

Using KKSB Rock 5B Case with Heatsink enclosure, now with a fan blowing to the inside of the case on top of the enclosure.

Still using the orignal RADXA POWER PD 30W.
