Hello here, exactly the same issue here with my fedora 32. I also have my /home mounted in NFS4 + Kerberos. Issue is introduced with 5.6.14-fc32, but still present in 5.6.15 & 5.6.16 If I boot with my old 5.6.13-fc31 it's working fine. Symptom: same kind of error messages in dmesg, NFS mount is totally frozen until reboot.
