[c-nsp] 6509 crash on loss of power to power bay 1

[Rick Kunkel]

Hello all,

Many thanks for help in the past.  I'm hoping someone will have something 
enlightening about this.  TAC and Bugfinder are turning up little, so I 
dunno what the chances are, but here it is...

I'll paste a bunch of version and module info at the bottom of this email, 
so as not to clutter the part that peple are more likely to read here.  
Essentially, what's happening is that when power is lost to Power Supply 
1, the router crashes.  [System returned to ROM by power-on (SP by error - 
a Software forced crash, PC 0x4011EF5C)]  Power loss to PS2 doesn't cause 
it.  If I swap the two power supplies, it still does it on PS1.  In other 
words, if the power is lost to "bay" 1, for lack of a better word, it 
crashes.

Has anyone ever run into anything like this?  One thing to note is that 
the input AC appears to be a bit low.  I don't know if that could 
contribute.

Thanks much.  All the relevant info that's not overly verbose follows.

Here are the modules (modified "show mod"):
