Public bug reported:
Refine the fix created in
https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-
common/+bug/2083657
[ Impact ]
* This issue affects all Ubuntu OEM preloaded systems that are still utilizing
the OEM kernel, particularly those equipped with NVIDIA graphics drivers.
* Systems may fail to boot properly due to an outdated OEM kernel conflicting
with newer NVIDIA drivers, leading to a black screen on reboot.
[ Test Plan ]
* To verify the fix, ensure that the file `/etc/default/grub.d/oem-flavour.cfg`
is successfully removed from the affected system after applying the update.
* After the system reboots, check that it boots into the general HWE kernel
rather than the OEM kernel.
* Idempotency Testing:
- Perform the upgrade multiple times on the same system to verify that the
upgrade process is idempotent, ensuring that repeated upgrades do not result in
unexpected behavior or changes.
* Non-OEM System Testing:
- Test the upgrade on a system without OEM kernels to ensure that the upgrade
does not affect systems that are not preloaded with the OEM kernel.
- Confirm that the system continues to function normally and boots into the
correct kernel after the update.
[ Where problems could occur ]
* Removing `/etc/default/grub.d/oem-flavour.cfg` may cause systems relying on
the OEM kernel for specific hardware compatibility to lose access to certain
OEM-specific optimizations.
* There is a low risk that after removing the OEM kernel, some hardware
features may not function as expected if the general HWE kernel does not fully
support them.
