Public bug reported:
[ Impact ]
See attached error log (make.log)
[ Test case ]
Install the latest linux-6.14 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt install linux-generic-hwe-24.04-wip
Install openafs-modules-dkms
$ sudo apt install openafs-modules-dkms
Load the module:
$ sudo modprobe openafs
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
[ Regression potential ]
We may experience regressions in systems that are using the openafs
drivers, especially with kernels >= 6.8 kernel.
