Conference 49.910::kav30

    Hi Marino ,
    
    since you have the latest revision of the KAV30, the problem I was
    thinking about we once had with VME-irq's and SCSI are already solved.
    Therefore I currently have no idea what your problem could be...
    could you post the following information:
    
    - ebuild .dat file
    - complete configuration in the crate (e.g. slot #, irq-level, vector
    and base address of all the boards you have in there ?
    
    Thanks and best regards,
    
    Thomas
    

Hi!

IRQ used are 1 for Digital I/O
             2 for IC40
    
    IC40 is a Frame grabber (OS/9 board handled by KAV30 driver as I/O port
    for the application.
    
    
    ciao,    MARINO

    Hi,
    
    we can not see anything unusual with this, so the only explanation we
    have is the following:
    
    VME-irq's have higher priority than SCSI, so if you have an VME irq,
    SCSI processing is stopped - but once the VME-irq is done, SCSI should
    resume operation. Normally this is transparent to the user and works
    fimne... How many VME-irq's do you get pwr second ?

    Thanks Thomas,
    I spent time to review and review the code (I also tried to change from
    autoload to no autoload the driver, change the vector and more ...) but
    with no better result; as soon as I get an interrupt from one channel
    of digital I/O board I go into the problem.
    
    ciao,   Marino
    

    Hi Marino,
    we will try to reproduce your problem in our lab... currently we have
    no idea what the problem is - we will contact you by mail in order to
    get more details of your application. I hope that we can solve your
    problem soon!
    
    best regards,
    
    Thomas
    

    The problem described was tested with several combinations of VME IRQs
    but the problem is not reproducible.
