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

Would it be possible to update to the latest BIOS? Or can you please try the kernel parameter "intremap=no_x2apic_optout", also please provide output of the command "ethtool -i em1 ; ethtool -k em1", thanks! -- 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.
