Thanks for letting us know Jahn and it's great to see that the problem is
resolved.  It may be that the chipset can "keep up" with some interfaces and
not others.  Or maybe there's something about the traffic pattern from the
RME which trips up the O2 chipset.

For what it's worth, I've found the following comment in a post on one of
the RME forums:

  We [RME] own a Dell with 02 Micro chip. This particular one is even worse
  than the Ricoh one. Not recommended!

The post is from 2008 and I'm not sure what "Ricoh one" he's referring to,
but the general indication is that trouble with such chipsets isn't entirely
unheard of.  View the whole thread at

It seems that at least some of the issues may be related to specific laptops
and/or BIOS versions.

Thanks for doing that - it would have been my next step. :-)
