Seems to be related to the URL above. If you have any help to provide
there, feel free to do so, nobody seem to be able to reproduce easily so
far.

For the record, this "timeout for 2 seconds" error in I830WaitLpRing is
the same than the old "now is -705835238, start is -705837239" (the
error message has been replaced 2 months ago in commit
8db28aeaa6e908017b40bd9180f144a2972f6278).
