Bug#897599: regression in userspace on linux-image-4.9.0-6-amd64

[rolnas@gmail.com]

Package: linux
Version: 4.9.88-1

After linux kernel upgrade from linux-image-4.9.0-5-amd64
(4.9.65-3+deb9u2) to linux-image-4.9.0-6-amd64 (4.9.88-1) there we found
some regression in userspace.

1) rpc.gssd cannot start at boot, but starts later manually. No error
message, only systemd is complaining about timeout. I found a workaround
to start with -f (we need change Type=forking to Type=simple).

2) sssd don't work at boot, service shuts on first error, but later it
works. "getent passwd username" is hanging on boot time, but later,
after first failure, starts to work. No workaround found.

All those are working fine with older kernel. No idea what change could
cause this.

All of them are in Ubuntu 16.04 and Debian 9 based KVM VMs (up to date).
