For everyone who has the same problem and who absolutely needs to use
NFS4.1 or NFS4.2, there seems to be a simple solution. If the NFS server

Hi Mehmet,
I was just able to send the sos report after crash with NFS debugging turned on
to Ubuntu Support (case 00398586).
I have not testet your unofficial kernel version up to now, because I need a
procedure to reproduce the crash after minutes and not after days.
Which procedure should I fo
d and many processes to reproduce the problem? I also need this
process for approval with us.
I'm currently trying to find a stable workaround.
Best Regards
Peter Schubert

Public bug reported:
Since August 19th we have been struggling with irregular crashes on our
NFS server.
Our experiences with NFS server crashes are:
- We were able to reproduce the crashes in our production and test environments
with NFS4.2. Rarely after minutes, sometimes after hours or days,
We installed the unofficial kernel 6.8.0-46-generic-nfs on several NFS client
servers on Saturday and have been testing it with high IO loads since then.
Unfortunately the server crashed again after about 40 hours with "rcu: INFO:
rcu_sched self-detected stall on CPU".
The kernel 6.8.0-46-generi
