On Linux kernel 4.16.8 (using Arch Linux) if I eject a USB 3.0 device from my system (unplug or "udisksctl power-off --block-device /dev/sde), it freezes instantly with a null pointer error in XHCI. I've been unable to successfully capture a kernel log of the error (and my cameras did not return usable results) and the screen begins scrolling near-immediately with hung processors in a VT.  I have done a git bisection (between 4.16.7 and 4.16.7) narrowing it down to the following commit. Sending this both here and to the stable list, apologies if I'm doing it wrong. I am not subscribed to this list, so CC me please if replying to this.


Thanks, I got a similar report earlier, with a soltion.

I'll send it out in a few minutes
