@Sam, I will be uploading a fixup Hirsute kernel (with the 4 additional
patches picked) to
https://launchpad.net/~smb/+archive/ubuntu/temp01
That showed the same regression in ADT logs as Groovy did. So if it
works there it would help Groovy as well. If you could rerun the linux
regression tests
For reference these are the upstream SHA1 references:
0d7a7b2014b1 ipv6: remove extra dev_hold() for fallback tunnels
48bb5697269a ip6_tunnel: sit: proper dev_{hold|put} in ndo_[un]init methods
6289a98f0817 sit: proper dev_{hold|put} in ndo_[un]init methods
7f700334be9a ip6_gre: proper
>From quick scan: this seems to affect all hirsute and groovy (5.11 and
5.8) kernels. For Focal (5.4) and Bionic (4.15) the follow-up stable
commits appear to be applied at least for the 2021.06.21 cycle.

Actually this might need all 4 of those:

b0a78d4b8768 ip6_gre: proper dev_{hold|put} in
To say above is in hirsute. Not sure all 4 are for Groovy, too.

Title:
test_pmtu_vti4_link_add_mtu() test from net/pmtu.sh in
Thanks for the report!! We may be missing this patch:
https://git.kernel.org/linus/0d7a7b2014b1 ("ipv6: remove extra
dev_hold() for fallback tunnels")
It has a fixes tag for upstream 40cb881b5aaa, which was merged in our newer 5.8
kernels - can you test with the fix @cypressyew and let us know?
