Only difference is that now the entire box locks up. The error is almost the same eth1: hw csum failure.

I would be happy to rerun the test with that turned on, given some minor direction. Regards, Michal Please reproduce with a more recent kernel? Um, I thought 2.6.23rc WAS pretty recent. :-) I'll check if there is something newer in the repository now. -J Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos more. http://mobile.yahoo.com/go?refer=1GNXIC - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Does the error happen right away (ie all packets have bad sum), or is it sporadic (ie some magic packet or race in hardware). Also are you using regular (1500) or jumbo (9000) mtu? Regular MTU - 1500. It runs fine for normal stuff, ssh etc, but a big sftp will break it every time. My usual test is to sftp a linux distro ISO from another machine to it. Need a vacation?
