--- Comment #2 from Peter Eriksson <pe...@ifm.liu.se> ---
This is a really annoying bug that we've also seen. I do not think it's related
to iSCSI though (since we aren't using it). Disabling TSO seems to help (but
also severly reduces transmission speed - in our case it drops from around
10Gbps to 3Gbps without TSO).
I our servers are SMB (and NFS, but not much yet) servers. Dell PowerEdge
730xd.

I managed to login to the server after a while and disable TSO and then things
started working again.
Would using the Intel-provided (instead of the 11.1 one) driver and firmware
(from their web site) help with this issue?
