hang again. =) I'm unsure whether v7.2.x already automatically disables TSO for 100mbit speed link, probably not. It should. Please try our updated driver from http://e1000.sf.net/ (7.3.20) against the same kernel. There are some changes with regard to the ich8/TSO driver that might affect this, so re-testing is worth it for us. also, please always include the full dmesg output. Feel free to CC e1000-devel@...ts.sourceforge.net on this.
