Comment 28 for bug 1971151

Hi Sumit

I did link an older version of the source but the debs were built from the correct source below:

https://code.launchpad.net/~mreed8855/ubuntu/+source/linux/+git/jammy/+ref/mpi3mr_bsg_support

It is inconsequential because the patch that updates the version is included in the debs and in both source versions.

I think I do know what happened as to why the latest version of the driver did not load. I suspect that the kernel I built is older than the current version of the kernel that is deployed in new installs of Jammy. If this is the case it may not properly install or become the default kernel to boot when it is installed. The way to fix this is to modify grub so you can properly install and then select the older kernel.

Steps
1. Modify /etc/default/grub.d/50-curtin-settings.cfg and change GRUB_DISABLE_OS_PROBER="true" to false.

2. Modify /etc/default/grub and change GRUB_TIMEOUT_STYLE=hidden to menu and GRUB_TIMEOUT=0 to 1.

3. Sudo grub-update2

4. Reinstall the kernel debs. sudo dpkg -i (this should also re-run update-grub2)

5. Reboot and from console select the correct kernel 5.15.0-47-generic #53

6. This is not the ideal way to do this, and in the future I will rename the built kernel in such a way that will prevent this from happening, however it should work fine for testing purposes. If you have any issues let me know.
