Do you get the same problem when you run 2.6.21 with 7.5.5.1 or 7.3.20 ? > This happens also with the 7.4.35 and 7.5.5 driver from the intel side. > The driver 5.7.6 from kernel 2.4.33.3 and the 6.1.16 from intel works > very well on this hardware. > Also other gigabit nics we use didn't have this problem. > Is this issue already known? this is the first time I have heard this issue. > Is there any solution yet? I'm not that good :) Can you file a bugreport on e1000.sf.net and attach the usual (ethtool -e, dmesg, ifconfig -a, lspci -vv) debugging output and problem description for us? I'll try to see if I can have our labs setup a repro case, which might be hard given the adapter type, but we will do our best. Auke
