[ Test case ]
Install the latest linux-6.11 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt update
$ sudo apt install linux-image-6.11.0-12-generic \
linux-modules-6.11.0-12-generic \
linux-modules-extra-6.11.0-12-generic \
linux-headers-6.11.0-12-generic
Install rapiddisk-dkms:
$ sudo apt install rapiddisk-dkms
Load the module:
$ sudo modprobe rapiddisk
$ sudo modprobe rapiddisk-cache
The same procedure should be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Backport the package from Oracular to properly support the new 6.11
kernel ABI.
[ Regression potential ]
We may experience regressions in systems that are using rapiddisk with a
kernel >= 6.8.
