[vfio-users] NVME M.2 SSD broke my vfio setup

[Mogliii]

Thank you for that information. Do you have any issues with the ACS
override?

I once built kernel with ACS override manually, but I would like this
process to happen automatically when ubuntu releases a new kernel. Could
you point me to some debian dokumentation about this and I might be able
to adopt it for my ubuntu?

Or what is the general procedure to make this as automatic as possible?
