            Bug ID: 220872
           Summary: ixv driver 12.0 crash in AWS/EC2
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: jwjerni at g.clemson.edu

I have created a few instances in AWS using the lastest AMI for the CURRENT
branch:
FreeBSD 12.0-CURRENT-amd64-2017-07-11 (ami-847b7992)

A couple of these have started up just fine, but the rest of the instances are
inaccessible due to the network driver crashing on startup and rendering the
machines inaccessible by SSH. I have one working instance, but even creating
more based off of that configuration are failing to start networking properly.
Restarting the instances does not fix the problem. I have pulled the following
logs from the AWS web console for two m4.10xlarge instances with the same
configuration and AMI.

Working instance:
ixv0: <Intel(R) PRO/10GbE Virtual Function Network Driver, Version - 1.5.13-k>
mem 0xf3000000-0xf3003fff,0xf3004000-0xf3007fff at device 3.0 on pci0
ixv0: Using MSI-X interrupts with 2 vectors
ixv0: Ethernet address: 0a:2f:e8:85:2f:38
ixv0: netmap queues/slots: TX 1/1024, RX 1/1024

Malfunctioning instance:
ixv0: <Intel(R) PRO/10GbE Virtual Function Network Driver, Version - 1.5.13-k>
mem 0xf3000000-0xf3003fff,0xf3004000-0xf3007fff at device 3.0 on pci0
ixv0: MBX API 1.2 negotiation failed! Error -32

The error appears to be coming from sys/dev/ixgbe/if_ixv.c in the source. Let
me know if I can provide any further information.

Thanks,
James
