It means the hardware couldn't keep up with the serial load.  I started
seeing that recently on my -stable box at home after I upgraded the
kernel, and I *never* saw it before.  I'm not sure why, but it might be
related to the SPL changes Peter/Bruce made.  (Just guessing).

It's mostly harmless, but annoying since the only load I have is *ONE*
SLIP connection running at 115K on a 486/66 which is mostly unloaded
when I get these messages.
