kernel softlockup/networking/e1000

[Denys Fedoryshchenko]

At the beginning - kernel is with "gentoo patched", but i checked, there is 
nothing major and almost none from patched code used on this router (there is 
almost no networking patches, except e1000e support, small GRE fix and few 
wireless things, which is not used).

Looks like you're hitting an old bug where there is a race between something
running in the background continuously hitting ethtool ioctls and the driver's
watchdog.

Can you identify which program is doing the ethtool command? That would help.

Please re-test with the latest git tree  - I believe that we just recently fixed
this bug, and I'm almost sure that your kernel does not have that fix.

Cheers,

Auke
