            Bug ID: 243612
           Summary: xhci controller sometimes stuck in an endless error
                    loop
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: usb
          Assignee: usb at FreeBSD.org
          Reporter: d8zNeCFG at aon.at

Scenario:
- Lenovo W520 laptop
- grep -i xhci /var/run/dmesg.boot:

xhci0: <NEC uPD720200 USB 3.0 controller> mem 0xd4100000-0xd4101fff irq 18 at
device 0.0 on pci5
xhci0: 32 bytes context size, 32-bit DMA
xhci0: Unable to map MSI-X table 
usbus1 on xhci0
ugen1.1: <0x1033 XHCI root HUB> at usbus1
uhub2: <0x1033 XHCI root HUB, class 9/0, rev 3.00/1.00, addr 1> on usbus1

- Trying to connect USB 3.0 devices; in this case, WD My Book 25EE 4007
7630885MB

Result:
- Sometimes, instead of normally probing and attaching the USB devices, the
controller gets into an endless loop; here the result (from /var/log/messages)
with leaving the external devices in for some seconds, then removing it, then
trying to plug it again, the removing it:

- This condition can only be remedied by rebooting the machine.
