Could be related but i have different symptoms. I can still reboot the pi and nothing hangs (except IO to the disconnected drives of course).

I have tried more things to debug this. It seems that on raspi-os with the same setup the USB controller does not crash but some seagate drives still disconnect randomly. They keep spinning up and disconnecting after that. Only fix is a reboot.

It also happens less frequently on USB2. I don't get why. Sound like a thermal issue to me, but i also have a fan in place for the external HDDs. My second guess would be power supply, but i have a 5A one connected to the hub, and it's only the seagate drives that disconnect.

Anyway, while using raspi-os still does not solve my problem it at least does not crash the USB controller.
Maybe ubuntu needs to update the raspi firmware or kernel to also get this behaviour?
