Hi Andrew,
I believe this is the same as bug 2078704. We narrowed it down to
"sunrpc: exclude from freezer when waiting for requests:" that fixed the
issue. It should be present in 5.15.0-121-generic or later.
Thanks,
Matthew

Title:

Status in linux package in Ubuntu:
New
Bug description:
When I have one of my NFSv3 mounts active, the system will fail to go
to sleep. Kernel trace:
kernel: Freezing user space processes ... (elapsed 0.003 seconds) done.
kernel: OOM killer disabled.
kernel: Freezing remaining freezable tasks ...
kernel: Freezing of tasks failed after 20.003 seconds (1 tasks refusing to
freeze, wq_busy=0):

First appeared in linux-image-5.15.0-118-generic, present in linux-
image-5.15.0-119-generic, not present in linux-
image-5.15.0-117-generic.
Steps to reproduce:
* Boot linux-image-5.15.0-118-generic or -119
* Mount an nfs share. Ensure that lockd kernel module is loaded
* Put computer into suspsend, it will fail to enter suspend as the lockd task
will fail to freeze.
When lockd module is not loaded, system is able to go into S3 without
issue.
