[ Test case ]
Install the latest linux-6.17 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge
Install rapiddisk-dkms:
$ sudo apt install rapiddisk-dkms
Load the modules:
$ sudo modprobe rapiddisk
$ sudo modprobe rapiddisk-cache
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
Install the latest kernel on Questing and Resolute:
Install rapiddisk-dkms:
$ sudo apt install rapiddisk-dkms
Load the modules:
$ sudo modprobe rapiddisk
$ sudo modprobe rapiddisk-cache
[ Fix ]
Custom patch from rapiddisk (https://github.com/pkoutoupis/rapiddisk/):
-debian/patches/0001-Page-struct-no-longer-has-index-member-so-
switching-.patch
[ Regression potential ]
We may experience regressions in systems that are using the rapiddisk
drivers, especially with kernels >= 6.8 kernel.
