Try a kernel before 5a87b7a5da250c9be6d757758425dfeaf8ed3179

from the tests I've done that one showed the least or no corruption if
you count the empty /etc/env.d/03opengl as an artefact

(I tested 3 commits in total)


1) 5a87b7a5da250c9be6d757758425dfeaf8ed3179

2) 1de3e3df917459422cb2aecac440febc8879d410

3) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc

1 -> 3 (earlier -> later)
