We had an odd bit of misbehavior from one of our Eagles today:  it hung,
with the READY light off, not doing anything.  Furthermore, when we tried
shutting it down, it wouldn't response to the front-panel switch!  Flipping
the START switch off did nothing; the START light stayed on, and there was
no sound of the disk shutting down.  We finally pulled the circuit breaker
for a moment.  On powering it back up, it seems fine.  Does anybody know
what gives?

[Before you ask, we did look at the LEDs in the back.  But it's been so
long since we had to bother, we forgot that useful information can be
extracted by manipulation of the STATE switch.  The URDY light was on,
the ONCYL light was off, none of the other LEDs was on (nor was the
front-panel FAULT light), and the numeric display, in state 2, was
showing 6d as opposed to the normal 65.]

If it's relevant, the Eagles are about 9 months old and are on an SC31
controller on an 11/44 running pretty-much-V7.
