[5.4.y] Odroid-N2: USB did not work stable #396

Open pvizeli opened 4 years ago

pvizeli commented 4 years ago

If I start to add 2 USB device (i.e. zwave & zigbee) which are serial devices, the blue light start to going blink faster and the device going to be unstable. Without a plugin USB device, everything work fine. This is not happens with upstream 5.4 kernel.

With 5.4.32 it worked stable -> 40b58dcff55ee1046f6d69953b241ff27b92f749 Maybe the new pci device-tree changes? Also sdcards have issues with latest 5.4.35 update. But only N2, C2 and XU4 works fine

I fix the issue with revert the thermal patches: https://github.com/home-assistant/operating-system/commit/0db61e85b06c6298ac98de85deec921d403311c8

Currently, no clue what the issue is. Some users report HDMI issues other issues with USB. That patch fixes it. Special is, that not all devices are affected in the same way.

My patch with the latest 5.4 odroid branch (today) works on all our N2.
