1718.0. "DEFEA card fault" by 36677::GINGER (Ron Ginger) Thu Jun 15 1995 12:52

    We have 14 2100's, all with 2 FDDI DEFEA DAS cards. 
    
    We had a machine panic and crash. The stack dump showes it was in a fda
    interrupt service routine when it crashed.
    
    We tried to re-boot the machine and the console firmware could not
    complete the self test. We got thru the memory test but then  got to
    the following:
    
    Testing the system
    interrupt through vector 670 on cpu0
    C-bus read data parity error
    invalid C-bus address
    ....folowed by pages of stack dump.....
    
    The system would then re-start self test, only to encounter the error
    and dump again. We tried power off/on a couple times, but it continued
    to loop.
    
    About 30 minutes later  we re-booted an adajacent macine on the FDDI  
    ring, and this machine immediaetly completed self test, re-booted, and
    has had no error since.
    
    Is there any way a DEFEA card could 'remember' some kind of fault
    across a couple power cycles, then get reset when the ring did an
    initalize?
