If I recall, you were one of the two people that needed to switch to=0A=
"minorversion=3D1" to get rid of NFSERR_BADSEQID (10026) errors.=0A=
Is that correct?=0A=

Btw, using "soft" with NFSv4 mounts is a bad idea. (See the BUGS section of=
=0A=
"man mount_nfs".)=0A=
=0A=
If you have a hung NFSv4 mount, you can use=0A=
# umount -N /usr/home=0A=
to dismount it. (It may take a couple of minutes.)=0A=

Are you using any mount options with nullfs?  It might be worth trying to m=
ake the read-only mount into read-write, to see if that helps.  And what do=
es "jls -n" show?=0A=
