Package: nfs-common
Version: 1:1.3.4-4
Severity: important

Dear Maintainer,

rpc.gssd seems to have problems setting up the machine credentials
cache since kernel 5.10

we see the same problem on amd64 (debian bullseye) and arm64 (raspberry using
debian bullseye). The server as a debian buster amd64. Kerberos is
provided by samba-ad-dc. Windows 2003(!!) to Windows 10 and Linux clients 
happily
work as domain members.

Test 1: run kernel 5.9, (auto)mount, working
Test 2: run kernel 5.10, (auto)moutn, ERROR 

Thanks for your attention
Jürgen
