Bug 1209457, please delete Bug 1209457

I am using rdiff-backup to backup all important files for about 10 years now. Target is an NFSv4 mount. Again in 5.14.21-150400.24.49-default this does not work properly any more: read and writes seam to be affected. When booting back to 5.14.21-150400.24.46-default everything works fine again which eliminates all reasons related to python or rdiff-backup itself. 
My kernel is set to preempt=full.
Unfortunately the error happens quite discretely: no error messages in dmesg or journal appear.
In some 15.x version NFSv4 client code too was broken by some kernel update once: directory listings (which in my case contain about 15k entries) suddenly where truncated. I hope this isn't some recursion?
