Bug#859190: linux-image-4.9.0-2-amd64-unsigned : NFSv4 client error
Package: linux-image-4.9.0-2-amd64-unsigned
Version: 4.9.18-1
Dear maintainer,
here is a warning I observed on a NFSv4+Kerberos client.
The taint comes from this previous error message:
[ 0.653706] scsi_mod: module verification failed: signature and/or required key missing - tainting kernel
