Did you ever get any help on this issue? The below failure shouldn't cause a system halt. You are getting a reset which I wouldn't expect unless something else triggered it.
A bigger question is why are you getting reset during runtime? What kind of traffic do you normally do? -----Original Message----- From: Kai Iskratsch [mailto:kai.iskrat...@robart.cc] Sent: Monday, May 18, 2015 5:27 AM To: e1000-devel@lists.sourceforge.net Subject: [E1000-devel] system hanging after i40e kernel errors i am using the version 1.2.38 of the i40e stable downloads on opensuse 13.2 (kernel Konsole outpu3.16.7-21 3.16.7-21) and i seem to get a complete system hang about once a week. it is always preceeded by at least 3-4 of these page allocation failures in the i40e module within very short time (less than 1 second) logfile output of one of these page allocation failures: May 18 09:57:00 srv2 kernel: kworker/0:0: page allocation failure: order:6, mode:0x80d0 May 18 09:57:00 srv2 kernel: CPU: 0 PID: 23490 Comm: kworker/0:0 Tainted: G O 3.16.7-21-desktop #1 May 18 09:57:00 srv2 kernel: Hardware name: ASUSTeK Computer INC.
