It looks like my Karma now refuses to talk to any network I plug it into. I had 1 known switch it would actually talk to (due to the known network problem). Now for whatever reason, it refuses to talk to any of my 5 switches in the house, nor will it work directly cabled to my Powerbook and Dell laptops.

So, what component is likely bad? Is most of the ethernet in the dock, or in the Karma? Thankfully Best Buy does still carry the Karma online, so my replacement plan should still get me an exact replacement instead of an iPod or similar.

And yes I know USB2 works fine, but it only works for me at 1.1 speeds on my Powerbook due to having to use Virtual PC and RMM. I'd rather just stick to using JEmplode on my Mac to keep my hierarchical playlists. At least until mass storage support is added one day.

Also as a side note the download page for 2.90 says the Taxi program is included, but it is missing from the installer.

I noticed that too. That'd be nice to have.

As an update to this, looks like the network is still working like it normally does if I use a long enough cable. Kinda silly to have a 50 ft cable for the Karma when it sits on my desk right next to the 5 port switch I use, but I suppose it will do for now to allow cross platform transfers again.

As tfabris says, it's an oscillator tolerance combined with a bug in the PHY silicon. The issue is in the player, not the dock, though we only ever saw occasional issues with certain hubs - it talked fine to almost everything. If it's stopped working with *everything*, this might not be the same issue.
