I'm getting "missing interrupt" messages from ATAng on one of my older
PPro200 machines that was stable with a June kernel, but is not with
an October 22 kernel.  I don't know that they're related, and I
haven't had a chance to look more deeply into it yet.

These are the only suspicious messages that make it into the log.  The
de0-related messages have always happened with no harm.

Oct 23 16:52:21 mole kernel: de0: abnormal interrupt: transmit underflow (raising TX threshold to 96|256)
Oct 23 16:54:14 mole kernel: de0: abnormal interrupt: transmit underflow (raising TX threshold to 128|512)
Oct 23 17:07:31 mole kernel: de0: abnormal interrupt: transmit underflow (raising TX threshold to 160|1024)
Oct 23 22:59:41 mole kernel: ad2: WARNING - WRITE_DMA recovered from missing interrupt
<I noticed the hang and rebooted _at_ 23:10>

It's an old machine, but it's never had any serious problems before.
Now it hangs hard every day.  It doesn't panic or drop into DDB.

I've configured a console that will allow invoking DDB with
ctrl-alt-esc, so I'll try to gether more information.
