In this case I think only some command timeout(If I remember well it
worked for a bit and then stopped working)
But I'm sure that you can ping with the command timeout and have some
transfers etc...

With power saving disabled it works fine,until the battery goes out.
Disabling power saving also stop the flow of timeout messages...

No I just used the patches that weren't mine
I took them from openpandora wireless repository,looked if they were
already included,and include the one that weren't.
