Strange message - eth0: too much work in el3_rx

["Moore, Paul" <Paul.Moore@uk.origin-it.com>]

I'm getting strange messages on the console of my Debian machine, namely

    eth0: too much work in el3_rx

Can anyone give me any hints as to (a) what it means, (b) whether it
indicates a problem, and(c) how to get rid of it (as it corrupts my working
screen).

Thanks,
Paul Moore.

PS If I need to supply any more information, let me know - I'm not sure what
might be useful...
