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 + 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 + 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 - --- + 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.
