But, now it's dropping characters with a port speed of 57600, and I am also getting irq overrun errors from the kernel too now. This is actually much better than I had before. With a port speed of 2400, I do not drop characters. Here's the message that I got: sio4: 2374 more interrupt-level buffer overflows (total 2374) test# vmstat -i interrupt total rate irq1: atkbd0 6 0 irq6: fdc0 10 0 irq14: ata0 1120 1 irq15: ata1 47 0 irq17: sio4 415 0 irq19: sis0 sis2 970 1 cpu0: timer 1764263 1998 Total 1766831 2000 test# >From what I can tell, PCI slot 3 and sis0 on the mainboard are both tied to irq 19, which probably was the whole problem. But now I'm having an irq latency problem. This is progressing well though. -- Daniel Rudy
