This is a known problem with the ep driver. The immediate workaround is to ifconfig the interface down and up again. A more permanent workaround is to set NMBCLUSTERS to some large value, such as 4096 or 8192, in your kernel configuration file. The Correct Solution (tm) would of course be to identify and correct the error in the ep driver. -- Noone else has a .sig like this one.
