[CentOS-virt] NIC Stability Problems Under Xen 4.4 / CentOS 6 / Linux 3.18
I have three different types of CentOS 6 Xen 4.4 based hypervisors (by hardware) that are experiencing stability issues which I haven't been able to track down. All three types seem to be having issues with NIC and/or PCIe. In most cases, the issues are unrecoverable and require a hard boot to resolve. All have Intel NICs. Often the systems will remain stable for days or weeks, then suddenly encounter one of these issues. I have yet to tie the error to any specific action on the systems and can't reproduce it reliably. - Supermicro X8DT3, Dual Xeon E5620, 2x 82575EB NICs, 2x 82576 NICs Kernel messages upon failure: pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0018 pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Transaction Layer, id=0018(Receiver ID) pcieport 0000:00:03.0: device [8086:340a] error status/mask=00002000/00001001 pcieport 0000:00:03.0: [13] Advisory Non-Fatal pcieport 0000:00:03.0: Error of this Agent(0018) is reported first igb 0000:04:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0400(Receiver ID) igb 0000:04:00.0: device [8086:10a7] error status/mask=00002001/00002000 igb 0000:04:00.0: [ 0] Receiver Error (First) igb 0000:04:00.1: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0401(Receiver ID) igb 0000:04:00.1: device [8086:10a7] error status/mask=00002001/00002000 igb 0000:04:00.1: [ 0] Receiver Error (First) This spams to the console continuously until hard booting. - Supermicro X9DRD-iF/LF, Dual Xeon E5-2630, 2x I350, 2x 82575EB igb 0000:82:00.0: Detected Tx Unit Hang Tx Queue <1> TDH <43> TDT <50> next_to_use <50> next_to_clean <43> buffer_info[next_to_clean] time_stamp <12e6bc0b6> next_to_watch <ffff880006aa7440> jiffies <12e6bc8dc> desc.status <1c8210> This spams to the console continuously until hard booting. - Supermicro X9DRT, Dual Xeon E5-2650, 2x I350, 2x 82571EB e1000e 0000:04:00.0 eth2: Detected Hardware Unit Hang: TDH <ff> TDT <33> next_to_use <33> next_to_clean <fd> buffer_info[next_to_clean]: time_stamp <138230862> next_to_watch <ff> jiffies <138231ac0> next_to_watch.status <0> MAC Status <80383> PHY Status <792d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> This type of system, the NIC automatically recovers and I don't need to reboot.

This looks like the NIC decides something is wrong, throws off an PCIe error and then resets itself. It could also be an error in the Linux stack which would "eat" an interrupt when migrating interrupts (which was fixed upstream, see below). Are you running irqbalance? Could you try turning it off? Did you have these issues with an earlier kernel?

If you enable the xen-testing repository in your CentOS-Xen.repo file (assuming it is pointing to xen-44 and not xen-46) then a 'yum upgrade' should replace all the needed packages. The actual path is here for the packages: https://buildlogs.centos.org/centos/6/virt/x86_64/xen-44/ Hopefully this helps.
