** Description changed: 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. lsb_release -rd Description: Ubuntu 20.04.2 LTS Release: 20.04 linux-raspi version: 5.4.0.1035.70 uname -a Linux pi 5.4.0-1035-raspi #38-Ubuntu SMP PREEMPT Tue Apr 20 21:37:03 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux lsusb (after crash) Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + --- + ProblemType: Bug + AlsaVersion: Advanced Linux Sound Architecture Driver Version k5.4.0-1035-raspi. + AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' + ApportVersion: 2.20.11-0ubuntu27.18 + Architecture: arm64 + ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/controlC0', '/dev/snd/pcmC0D0p', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + Card0.Amixer.info: Error: [Errno 2] No such file or directory: 'amixer' + Card0.Amixer.values: Error: [Errno 2] No such file or directory: 'amixer' + CasperMD5CheckResult: skip + DistroRelease: Ubuntu 20.04 + ImageMediaBuild: 20210201.1 + IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' + Lspci-vt: -[0000:00]---00.0-[01]----00.0 VIA Technologies, Inc.
