I am requesting advice diagnosing a R710 running xen on Debian Stretch panicking once a day.
The server will run fine for ~24h and eventually throw a Kernel Panic usually about bxn2. (Will put full panic below) System no longer responds and usually requires a reboot. After the reboot the system is fine but will eventually panic.
I have an identical server running server which does not crash when it has one or two vm's but will crash when all vms are run from the system. I also have another R710 with a H700 which is running ~10 vms without issue.
I am also having issues recreating the panic. At one point I was able to reliably crash the second server by loading the cpu to max and doing high IO. (sha1sum /dev/zero and dd).
The Dell R710 specs are as follows:
- 2x 4core cpu
- 72GB of ram
- SAS 6/iR Integrated Firmware Version : 00.25.47.00.06.22.03.00
- SAS6 passing through to 1x 1tb os disk, 2x 2tb disk in mdadm array (03:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08))
- Broadcom NetExtreeme 2 nic. (01:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20))
- All bios and firmware updated with lifecycle controller.
It is running Debian Stretch with the following details:
- GNU/Linux 9 \n \l
- Linux xen01 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u3 (2017-08-06) x86_64 GNU/Linux
- It is running xen-hypervisor-4.8-amd64 4.8.1-1+deb9u1 with 22 virtual machines.
- ii firmware-bnx2 20161130-3 all Binary firmware for Broadcom NetXtremeII
- mptsas version 3.04.20
- mpt3sas version 13.100.00.00
- ii bridge-utils 1.5-13 amd64 Utilities for configuring the Linux Ethernet bridge
So far I have tried the following (alone and in different combinations):
- Disable MSIX for bnx2. modprobe bnx2 disable_msi=1
- Disable MSIX for mpt3sas. modprobe mpt3sas msix_disable=1
- Added intremap=off to kernel and turned off Intel Virtualization via BIOS to avoid Intel 55x0 Chipset errata. https://support.citrix.com/article/CTX136517
- Lowered vm.dirty_background_ratio=5 and vm.dirty_ratio=10 to get around Linux Server Crashing with "INFO: task blocked for more than 120 seconds"
- Set nic rx higher and raised net.core.netdev_max_backlog=30000 as per https://unix.stackexchange.com/questions/37727/solving-ethernet-watchdog-timer-deadlocks
One example of a panic.

Any advice would be greatly appreciated. Thank you!
update 20170926 - Have updated second machine with 2 dual port intel nic cards and disabled bnx2 and machine still continues to crash. Without any domU's, the first machine has remained up for 6days.
