Comment 32 for bug 2009325

I have prepared a test kernel that reverts the file access cache-related commits.
Please follow these steps and give it a try:

1. sudo add-apt-repository ppa:chengendu/jammy-nfs-test
2. sudo apt update
3. sudo apt install linux-headers-5.15.0-67-generic linux-image-unsigned-5.15.0-67-generic linux-modules-5.15.0-67-generic linux-modules-extra-5.15.0-67-generic
4. reboot
5. uname -rv
   5.15.0-67-generic #74+test20230307b2h2cbb6062f8eb-Ubuntu SMP Tue Mar 7 23:16:16 UT

In the meantime, we will also work on figuring out the error.
