My Gentoo based Linux laptop which is still running the older kernel 5.3.15. A short while back, I had a failed attempt to upgrade the kernel to 5.4.2 as the disk which encrypted with dm-crypt couldn’t be decrypted on boot. Since the older kernel 5.3.15 was working fine and free time was I what I lacked of, it seemed logical to just not doing anything about it. Today while updating all the packages on my Gentoo laptop, I notice there was a newer kernel available: 5.6.3. So let’s try to install this newest kernel again and see if the issue with Luks/dm-crypt still persists. ...

Today I decided to upgrade the kernel (gentoo-sources) from 4.19.64 to 5.2.6 on my old ThinkPad X220. Apart from a few hiccups, everything went quite smoothly. I already have a blog post about upgrading the kernel on Gentoo, so I’ll skip many things here. First, ensure the sys-kernel/gentoo-sources-5.2.6 is installed: # emerge -av =sys-kernel/gentoo-sources-5.26 After the above package installed, we should be able to list it: ~ ❯❯❯ eselect kernel list Available kernel symlink targets: [1] linux-4.14.63-gentoo-r1 [2] linux-4.14.65-gentoo [3] linux-4.14.78-gentoo [4] linux-4.14.83-gentoo [5] linux-4.19.27-gentoo-r1 [6] linux-4.19.44-gentoo [7] linux-4.19.52-gentoo [8] linux-4.19.57-gentoo [9] linux-4.19.64-gentoo * [10] linux-5.2.6-gentoo Let’s select linux-5.2.6-gentoo as the version we’d like to switch to: ...

Lmod is not available in Gentoo’s portage. This blog post will document how I got Lmod installed on my Gentoo machine. First requirement is to install lua.
