Announcing OLPC OS 11.2.0 for XO-1 and XO-1.5

[James Cameron]

Does it also happen if you avoid updating packages?

(The update you did applied a new kernel and several other interesting
things that are on the forefront of development, not part of 11.2.0, so
my guess is you found a bug.)

Given that you can get to a root console from the white screen, there's
an opportunity to debug further.  For instance, check for an X process,
and if absent try "start prefdm".
