Paul, any progress on this?

BTW, there is also a report about a NFS related general protection
fault, see this thread:

https://lore.kernel.org/all/CAK8fFZ7rbh5o9XG1D5KAPSRyES-8W8AphxsLJXOWUFZK49i8fA@xxxxxxxxxxxxxx/

It was bisected to 4b14885411f74b ("nfsd: make all of the nfsd stats
per-network namespace") [v6.9-rc1, v6.8.10 (abf5fb593c90d3)]

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
