I have 486dx50 here at work I have configured to be a modem pool. I am running 1.1.5.1 with an STB 4-Com serial card set up to share interrupt 15. At first I had the card on IRQ 11, but I kept gettign 'strayint f' messages... thinking it was something flaky about the 4-Com; anyway, I moved the card over to IRQ 15 and the problem seemed to go away for a while... Now, I am getting some wierd messages that the sio manpage says is a problem with the bottom half of the sio driver. Here's an excerpt from dmesg: sio6: 5 more interrupt-level buffer overflows (total 5) sio6: 48 more interrupt-level buffer overflows (total 53) sio6: 128 more interrupt-level buffer overflows (total 181) sio6: 3 more interrupt-level buffer overflows (total 184) sio6: 78 more interrupt-level buffer overflows (total 262) sio6: 25 more interrupt-level buffer overflows (total 287) So far as I can tell, I am not losing any data, or at least haven't heard any customer complaints. Is this 'strayint f' a hardware problem that my sio driver thinks is an actual serial interrupt... If so, is there a problem just letting these strayint f's happen and moving my serial interrupt to something else?? Oh... here's how the kernel probes my sio stuff if it is of any use: sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A sio4 at 0x3e8-0x3ef flags 0x705 on isa sio4: type 16550A (multiport) sio5 at 0x2e8-0x2ef flags 0x705 on isa sio5: type 16550A (multiport) sio6 at 0x1e8-0x1ef flags 0x705 on isa sio6: type 16550A (multiport) sio7 at 0x1a8-0x1af irq 15 flags 0x705 on isa sio7: type 16550A (multiport master) The problem only surfaces when using the STB 4-Com ports (sio4-7). Any info would be great, as this is annoying, but isn't causing any real problems. THanks, Troy Curtiss, HW/SW Engineer, Merix Corporation Forest Grove, OR 97116
