Fixing “RPC: AUTH_GSS upcall timed out.” from dmesg ( Debian and other linux distro)

In case you see this in your dmesg then please read further. The issue is also giving slow connection ( first) time on a NFS share (takes ~30seconds ).

There is a bug (!?) in the NFS client configuration and it runs a module called rpcsec_gss_krb5.

You can check if this module is running with “lsmod”.

Solution : do not load the module :

as root type :

echo blacklist rpcsec_gss_krb5 > /etc/modprobe.d/dist-blacklist.conf

then reboot

Problem solved : fast connection on NFS share and no dmesg error message.
