I also played too much with the configuration, here is what I missed:
- libgcc (openwrt configuration: Base system)
- udevtrigger (openwrt configuration: Utilities)
- special mount-utilities

It would be nice to come up with a suggested 'example' configuration for this device - the one most likely to work, and support as many devices as possible.  If that were included in SVN it would be extremely useful!

The second one is still a rather crude hack. If anybody has a better idea, go ahead..

Well... maybe.  I've updated the ticket with some thoughts.  The probe comes into inline_map_read()
and attempts to read memory which (I assume) causes a bus-error.  This is understandable
because this memory doesn't exist on the BR-6104KP.  We could add a check at the start of
inline_map_read() to see if the requested offset is more than 2MB (0x200000) and return
zero if so.  That's a less intrusive 'hack' and works fine on my Edimax, but I've no idea
of the implications for other boards.

The discussion might have continued from here.
