We use the TIP810/XY9660 (actually Acromag 9670) combination at here at SPEAR.

I don't know if this will fix your problem but we had to make changes to both the TIP810 and XY9660 software so that in the TIP ISR, interrupts are disabled before the interrupt is serviced and then reenabled/cleared afterward.  I also removed the automatic reset clear on bus error from the ISR and instead check every 2 seconds for the bus error and do a canBusReset via a sub record.  We had a problem with the ISR continually firing and taking up all the CPU when certain cables were disconnected or connected incorrectly.

If you are interested, I will send you the changed t810ISR routine plus the xy9660 irqCmd routine that now supports ipac_irqClear and ipac_irqDisable.
