I installed the 22.04 Beta on two test machines that were running 22.04 without issues before. One of them exports two volumes that are mounted by the other machine, which primarily uses them as a secondary storage for ccache.
After being up for a couple of hours (happened twice since yesterday evening) it seems that nfsd on the machine exporting the volumes hangs on something.
From dmesg on the client (repeated a number of times):
[ 6596.911785] RPC: Could not send backchannel reply error: -110
[ 6596.972490] RPC: Could not send backchannel reply error: -110
