This is because the alpha port doesn't currently support 'fast' interrupts which the i386 sio driver uses to be able to read characters from the port while the kernel thinks interrupts are disabled. I might add this support sometime but I'm too busy fighting other fires right now to think of it. One day, I would like to spend a decent amount of time profiling and tuning the alpha kernel... -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
