Title:
NFS deathlock with last Kernel 5.4.0-144.161 and 5.15.0-67.74
Status in linux package in Ubuntu:
Confirmed
Bug description:
After updating on the kernel
5.4.0-144.161 at Ubuntu 18 and
5.15.0-67.74 at Ubuntu 20,
we have a 100% CPU outlation and 20 to 30 Mbit traffic to the clients for our
NFS servers.
All clients are extremely slow when it comes to access to the NFS
resources.
Restart and use older kernel, fixed the problem.
Ubuntu 18 5.4.0-139-generic
Ubuntu 20 5.15.0-60-Generic
I don't have a NFS problem with this kernel.
Problem came with the last releas on March 3rd, 2023
