Bug Description
== Impact ==
Dell R340 fails to boot with UC20 pc-kernel snap because of unable to find the storage device.
== Fix ==
In this case, storage disks are connected through a controller enabled by kernel module megaraid_sas, hence the module must be presented in the initrd in order to make the system boot.
== Risk of Regression ==
Low. We're only adding an existing module into the initrd. The only downside may be the small increase of the snap size.

ubuntu- core-initramfs v40 has support for main & server features, which on x86 are enabled by default. The next snap build of pc-kernel in 20/ tracks should contain the required modules.
