are experiencing kernel errors
(http://www.newit.co.uk/forum/index.php?topic=455.0) and general
instability. This actually renders the plug
totally useless in client mode;, if there could be a fix released I
think most users as well as the distributors
would be most grateful.

Here is a dump of a dmesg output, showing some info about the error. I
myself frequently encounter these kinds
of errors so I you'd need more info about them, I'd be glad to help.
