Title:
Raspberry pi 4 USB controller randomly crashes
Status in linux-raspi package in Ubuntu:
Invalid
Status in linux-raspi source package in Focal:
Confirmed
Bug description:
My raspberry pi 4 running Ubuntu 20.04 server is constantly having trouble
the the usb controller.
I have 2 externally powered USB hubs connected that have a few HDDs plugged
in.
After a seemingly random amount of time (between 1 minute and 2 days)
the usb controller will crash completely. No USB devices are detected
anymore after that, i have to reboot the system.
I have tried:
* Providing a lot of cooling (metal case + desktop size fan)
* Switching the USB Hubs to a different brand
* Switching the power supply of the USB hubs
* Switching the power supply of the raspberry
Nothing helped, so i concluded that this probably is a kernel bug. I
think the USB controller should not crash at the very least.
I've attached my dmesg.
