PowerPC and dbpr

[ktsubota@keck.hawaii.edu (Kevin Tsubota)]

Hello PowerPC VME Users,

I'm in the process of uprading our 68k based VME system to
PowerPCs.  In particular MVME230x boards.

We're running EPICS R3.13.0Beta12.

Has any one seen this before? And if so what have you done
to fix it? Once this happens my only option is to reboot.

I have another ai record that is of DTYP=Soft Channel which
print without a problem.  This record is of DTYP=Bancomm 635.


I'm already disabling floating point underflows. 

Is it the general consensus to just disable floating point
exceptions as a whole?  Has anyone been looking into actually
getting to the root of these problems?  Or is it just me?

Thank you.
