I cannot reproduce the issue with "pcie_aspm=off". So it's related to https://bugzilla.redhat.com/show_bug.cgi?id=769626, maybe.
I see there are a bunch of errors reported right before the panic: sky2 0000:07:00.0: error interrupt status=0xffffffff sky2 0000:07:00.0: PCI hardware error (0xffff) sky2 0000:07:00.0: PCI Express error (0xffffffff) sky2 eth1: hw error interrupt status 0xffffffff sky2 eth1: ram data read parity error sky2 eth1: ram data write parity error sky2 eth1: MAC parity error sky2 eth1: RX parity error sky2 eth1: TCP segmentation error sky2 (null): hw error interrupt status 0xffffff BUG: unable to handle kernel NULL pointer dereference at 00000000000006d5 So I bet you are correct that this is a duplicate of bug 769626. I will close as a duplicate, but please reopen if the updated errata kernel that contains the fix from bug 769626 does not resolve the issue. *** This bug has been marked as a duplicate of bug 769626 ***
