Can you please test with the latest kernel? I see the following message from dmesg output.

So I disabled the onboard nic:s and bought a Intel Quad Card and use this instead. This server is now in production and can not be shutdown, so I'm afraid I won't be able to provide any additional information to this issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
