I'm trying to bring up an exiting EPICS application
on a PowerPC (Kinetic Systems V151 VXI)
running EPICS R3.13.2 and vxWorks 5.3.1
The existing software has been successully running
on an niCpu030 under EPICS R3.13.1 and vxWorks 5.3.1 
for quite awhile. 

I've run into a number issues with this PowerPC (VXI module):

1) missing lib vix functions such as SetMODID
2) missing or renamed unsolicited interrupt handlers 
   excStub and excIntStub.
  (from  devlib.c defaultHandlerNames[]) 
3) Is anything else tobe used in place of intHandlerCreate()
   for powerPC...or is this handled in some other way?
4) sysBusTas() seems to be different for the PowerPC but
   I can't find out what the difference is in the WindRiver
   manuals. Does anyone know how this function differs for the
   PPC?  When calling sysBusTas() from the allenBradley driver
   the following occurs:

SC_LOCK: calling sysBusTas  0xfcc0011d

alignment
Exception current instruction address: 0x0016f1a8
Machine Status Register: 0x0000b130
Data Access Register: 0xfcc0011d
Condition Register: 0x44000080
Data storage interrupt Register: 0x000000a0
Task: 0x1c2f2f8 "abScan00"
filename="../taskwd.c" line number=175
task 1c2f2f8 abScan00 suspended
initPeriodic: menuScan not present
value = 0 = 0x0

If anyone else has run into these problems with the PowerPC
I'd appreciate the any insite you gained.

       - Thanks,
