Package: usbip
Version: 2.0+4.19.160-2
Severity: important

Dear Maintainer,

usbip stops working (this has been a long standing issue) and not the
bug I'm reporting.

Previously, when this happens I would do rmmod usbip_host, modprobe
usbip_host and then it would start working again.

Now, when I do rmmod usbip_host after this happens I get a kernel gpf,
the reference count in lsmod goes negative, and the only thing that will
unstick things is a reboot (which is a problem as this is running on a
xen dom-0).

I'd never seen this issue prior to 11th Jan this year (and I've been
running with this setup since March 2020 (COVID WFH)

There was a xen hypervisor upgrade:
-rw-r--r-- 1 root root    616 Dec 16 06:25 /var/lib/dpkg/info/xen-hypervisor-4.11-amd64.list

which I rebooted to pick up on 18th December.

Due to the break I was not using usbip much until January.

First failure was January 11th:

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
