Comment # 5 on bug 1190007 from Takashi Iwai

We'll happily fix any bugs on Leap (if possible), of course, don't worry about
that.  The only problem is the lack of information.  Definitely more detailed
hardware information is needed.

So, at first, could you try to install TW image at first (or run with the live
image), and run hwinfo, and give the output?  Please use attachment on
Bugzilla.
Also, please give the output of dmesg, too.
