You are going to need to clarify some things since as far as I know we
never released a v3.0.8 driver, and the kernel in the bug below is a
version 2.6.40.8 which sounds more like a modified and possibly
backported Linux kernel since as far as I know Linus never released a
2.6.40 kernel version.

Sorry that my description was so inaccurate. I'm talking about a vanilla 
v3.0.8 linux kernel. Just renamed to 2.6.40.8.

In order to be able to assist you we will need some additional
information.  What Linux distro are your running?  Do you have the
latest updates from them?  Also have you tried running the latest
out-of-tree driver we provide at e1000.sf.net in order to verify if the
same issue occurs with that driver?

Linux Distri is Debian Lenny but we're running a self compiled vanilla 
3.0.X kernel. I haven't tried to use the up2date e1000.sf.net driver as 
3.0 is a long time supported kernel by greg - so all needed fixes should 
be backported or at least send to stable@ so that greg can have a look 
at them.

Thanks!

Stefan
