[Touch-packages] [Bug 1836721] Re: Black screen after updating mesa from 18.2 to 19.0 on i386 Ubuntu 18.04

[Timo Aaltonen]

okay, adding the revert again.. this should've been fixed in the kernel
after 18.04.2 but that didn't happen

since we don't support 32bit installs in newer releases, bionic is the
only one that will get this
