If you really wanted to verify you could try out the NIC's on a known good system again to see if the eeprom somehow got corrupted. That pretty much leaves us with ioremap returning an error. I'm not at all sure why your Ubuntu release would not like the way we are calling ioremap, but it might give you a place to start looking in Ubuntu changes.

Alright I solved it for me without pci=realloc=off or any patches with a Poweredge R920 In BIOS under Integrated Devices SR-IOV Global Enable = ENABLE -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1245938 Title: Intel x520 NIC's (ixgbe) stop working in 12.10, 13.04, 13.10 Status in linux package in Ubuntu: Confirmed Status in linux source package in Quantal: Won't Fix Status in linux source package in Raring: Won't Fix Status in linux source package in Saucy: Won't Fix Status in linux source package in Trusty: Confirmed Bug description: We have a server (Dell R715) with two Intel x520 NIC's.
