I have been seeing a number of silo overflows from a current kernel on a DX4/100 32Meg memory running ppp with the serial port rate at 57600. I had about 28 overflows in about an hour so nothing drastic. I never saw the "reduce trigger" message which I thought was suppose to appear when "silo overflow" messages appeared but a little looking reveals that the reduce stuff seems to be "#if 0" excluded... sooo I guess the initial trigger is FIFO_TRIGGER_14 and stays. Is the current solution to change the FIFO_TRIGGER_14 value in sioreg.h to something lower ? the ports probe as: sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A Jim
