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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930629 Title: Raspberry pi 4 USB controller randomly crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1930629/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
