Hi all,

I am having a strange new issue with the one of the raspberry pi 4b I have running at home. One of them failed/restarted for some reasons and it is now stuck at boot with the line:

Waiting for root device LABEL=writable…

I am booting this PI from USB. From what I can see the disk is ok. I can mount it on my laptop and access it correctly. The partition is labelled correctly. I tried to move it to another PI I have and I have the same error (I did this to remove the possibility it was the PI/USB port). I am pretty sure it is not the power that is the issue (since I am giving it more than enough).

All of this was working correctly until now (for months). Ubuntu may have updated something (my fault, I may not have disabled the auto-update) or something else could have broken.

I can try to point to the partition via UUID instead of the label, but something tells me that is not the issue. Did anybody encounter such an issue in the past or has any advice on how to debug it?

Thank you for your help and time.

    This might be completely diferent thing and it could be fixed already. Few months ago there was an update (debian bullseye i think) that messed up usb IDs on rasberries. It was mainsail os for 3D printer in my case and there was a fix that I never got working so I reinstalled OS and didnt update after that. I believe it was something with uuid, but better check yourself and never trust my words lol I hope someone knows more about that because it reminds me on the pain I had
