You might want to see if Ubuntu has pulled in the latest updates from the L=
inux
5.4.y stable/longterm series.  It looks like a number of race conditions in=
 the
NFS4 and packet processing layers were caught by syzkaller runs and fixed in
the last few 5.4 LTS updates.  My scenario, running 5.4.179, the oopses I
mentioned have seemingly left as mysteriously as they arrived, so my thinki=
ng
is the flaw was on the Linux-side and not on the FreeBSD-side.  It's possib=
le
those fixes may have resolved your case as well.
