I guess it slipped my mind since it wasn't me having the problem, heh.

Our X520 are still stable except for one recent problem, 2.6.18-238.9.1 -> 
2.6.18-238.12.1 broke it quite bad. With 238.12.1 our servers start dropping 
all incomming packets after a while. Sanity can be (temporarily restored with 
a "ethtool --negotiate ethX").

We are currently running a kernel that excludes:
 linux-2.6-net-ixgbe-fix-for-82599-erratum-on-header-splitting.patch
since that's what seems to break our setup.
