[Bug 1280462] [NEW] booting randomly fails on a dual-boot HP ZBook

[Martin Konopka]

Public bug reported:

affected computer:  HP ZBook 15, dual-booting Windows 7 and Ubuntu (64
bit)

It frequently occurs that the notebook freezes at the beginning of the
boot process. There are several randomly occuring issues:

* Sometime only the boot options are shown and no counter (of seconds of
time). The machine would not boot at all without pressing Enter. Even if
I press the key, the booting process usually stops shortly, showing some
text ("unable to ... transceiver", or something like, I do not remember
precisely).

* Sometime the text about the transceiver is shown in small letters and
with the purple background. In other cases the letters are much larger
and with black background.

* If the machine freezes while it is booting there is no help but the
long press of the power button.

* This time I was able to succesfully boot only after about 4
unsuccesfull attempts. Previous days it was about 50 % of unsuccesfull
attempts.

I have both the official kernel and also the lastest mainline build. The
booting issues occur with both of them.
