<pre>The timeout in the log happens on port B without eDP being enabled. There is a
known issue related to this discussed at the internal
HSD/1607152412
ticket which provides a workaround for the issue. The new programming sequence
needed for the workaround is described at
BSpec/Index/21257
I sent the corresponding patch to trybot:
