I know I should try to bisect this, but I don't have time and the randomness of the older kernel doesn't help. lspci: 0d:00.0 USB controller [0c03]: NEC Corporation uPD720200 USB 3.0 Host Controller [1033:0194] (rev 04) Kernel driver in use: xhci_hcd lsusb: Bus 007 Device 002: ID 152d:0539 JMicron Technology Corp. / JMicron USA Technology Corp. dmesg: [ 458.857081] usb 6-1: new high-speed USB device number 2 using xhci_hcd [ 463.857085] xhci_hcd 0000:0d:00.0: Timeout while waiting for address device command [ 464.728073] xhci_hcd 0000:0d:00.0: Stopped the command ring failed, maybe the host is dead [ 464.728073] xhci_hcd 0000:0d:00.0: Host not halted after 16000 microseconds.
