Hi James,
Thanks for reporting this. If you don’t mind, please file a bug here:
https://bugs.freebsd.org/bugzilla/enter_bug.cgi so this doesn’t fall off our
radar. We’re pretty sure we know what is happening and how to fix it.
Basically, the Linux PF driver that AWS is using doesn’t support mailbox API
version 1.2. The latest released Linux PF driver does, but we can’t control
what driver AWS uses. To work around this, we need a to add a failover to ixv
so it can fall back to 1.1.
Thanks.
Jeff

Hey freebsd net,
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

Malfunctioning instance:

The error appears to be coming from sys/dev/ixgbe/if_ixv.c in the source.
Does this appear to be an AWS specific issue or a more widespread one? Let
me know if I can provide any further information.
Thanks,
James
