Running out of buffers?

[Paul Goyette <paul%whooppee.com@localhost>]

I've got lots of memory, so I don't understand what buffers are not
available.  Ever since upgrading to my current system (sources dated
2018-03-20 11:25:00 UTC), I've been seeing these messages at random
intervals:

I never saw them with a previous kernel (from March 3rd), so it would
seem that something changed between the 3rd and 20th.

Is anyone else seeing similar?

Any clues on what changed?

The situation doesn't seem fatal (at least, not yet), but I'd like to
mitigate the condition before it gets worse.  :)

Thanks in advance for any suggestions.
