I'm still able to reliably reproduce this bug with the upstream 2.6.34 kernel drivers. If I use the drivers from sourceforge then the problem doesn't occur so there is definitely some driver issue that I have yet to find. I'll keep working the problem. - Greg ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
