--- Comment #2 from Richard Paul <rich...@primarysite.net> ---
We're seeing this now since we migrated out instance between instance types. 
Before we were using a c5.9xlarge instance and we recently scaled that back
down (we'd rebuilt and scaled up earlier in the year to deal with seasonal
load).

This instance is our primary db instance and the kernel panics seem to happen
either during the db dump process (which occur when we have the least amount of
DB traffic) or as has happened once so far, during the peak of the daily load.

Our log output is almost the same except as that already submitted, although
out current process line reads:

 ```current process              = 12 (irq269: ena0)```

The two previous reports had the same IRQ number and are on the same class of
instance types whereas we're on an M5 class instance type and get a slightly
different IRQ number.  Also, this was happening on 11.1p4 but we since upgraded
to p10 and the issue still is occurring.  I'm planning on upgrading a clone to
11.2p0 later this week to check out whether there's a new version of the ENA
(from here https://github.com/amzn/amzn-drivers/tree/master/kernel/fbsd/ena) in
this build.
