But Jesse found same problem on e1000. Bisect was relatively fast since it was either base net code or driver. Starting with 2.6.17, everything worked, and latest was busted. git bisect start net drivers/net/sky2.c Test was ipv6 slogin, then run dmesg. If that worked then run top and cause lots of other traffic by just doing a firefox open-tabs to blast lots of connections. Wanted to induce tcp-ipv6 to get congested. -- Stephen Hemminger <shemminger@...l.org> All non-trivial abstractions, to some degree, are leaky. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
