Re: [qubes-users] null pointer reference in kernel-latest in QubesOS 4.0

Hi,

Thanks for taking the time to have a look at my problem.

Interesting. I've not changed my setup and I'm currently writing this
while running the same configuration with dom0 5.4.143-1.fc25.qubes.x86_64
So I think this bug is new.  It was reproducable though. I've tried booting
the 5.13.6-1.fc25.qubes.x86_64 from kernel-latest at least five times in a row
to make sure it is no race condition.

I'm using an external keyboard, which is attached to my laptop through
one of it's USB controllers. Because I've usually mounted the laptop on
a stand, I don't want to be forced to use the internal keyboard to enter
the LUKS passphrase.

I will try blacklisting the xhci-pci as you suggested above and report
later, whether this made a difference.

Best regards, Peter Funk

libvirtd tried to assign the USB controller to a VM, and the USB controller
was already attached to the driver (xhci-pci) in dom0. The bug was
triggered while the driver was detaching itself.

Try one of the following:

- Temporarily detach the USB controller from the VM.
- Blacklist the xhci-pci driver in dom0. (create a .conf file with line
"blacklist xhci-pci" in /etc/modprobe.d)
