I don't think this was properly followed-up. According to bde@, PUC fast interrupts only work iff the system can obtain a unique IRQ. I had to use PUC fast interrupts on my i386 box as the multiport board lost a lot of interrupts. Due to IRQ sharing I cannot turn off there, I lose one out of four HME ports on the QFE I've got (which is acceptable for me). However, it doesn't appear the IRQs on the sparc64 systems are shared. Maybe someone wants to drag bde@ into the discussion... -- J"org Wunsch Unix support engineer joerg_wunsch@interface-systems.de http://www.interface-systems.de/~j/
