Hey Mathias, While the oops has been fixed in the latest kernels, as of 4.12.3, I'm still having issues where USB "stops working" after a while. If I restart, then after a long while, it stops working again. If I simply rmmod all the USB-related modules and modprobe xhci_pci, things work again, but pretty soon after -- maybe 15ish minutes -- it's broken again. If it's of any help, I'm often plugging and unplugging a USB hub with quite a few devices on it. The message in my dmesg this time isn't an BUG, like in the previous kernels, but rather this more subdued set of messages: [529153.583731] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [529159.215731] xhci_hcd 0000:00:14.0: ERROR mismatched command completion event [529159.215768] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [529159.423840] usb 2-2: device not accepting address 6, error -62 [529161.263641] xhci_hcd 0000:00:14.0: Timeout while waiting for stop endpoint command [529166.895725] xhci_hcd 0000:00:14.0: Command completion event does not match command [529166.895729] xhci_hcd 0000:00:14.0: ERROR mismatched command completion event [529173.551626] xhci_hcd 0000:00:14.0: ERROR mismatched command completion event [529178.671242] xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command .

Or should I try to gather more somehow?
