    Subject/proc/interrupts and serial
    Hi, 

    I have got four serial ports, 16550A type, which are correctly
    recognized and auto-configured (even auto_irq with 2.1.124) by the
    kernel, but the interrupts of ttyS2 and ttyS3 don't show up in
    /proc/interrupts, while their ioports do. This happens with both 2.0.35
    and 2.1.124. Any ideas? ttyS2 and S3 use irqs 10 and 15, respectively.
    2.1.124 is compiled with serial IRQ sharing, but I use different
    interrupts for each because of the other OS's flaws.

    emma1:/root # cat /proc/interrupts ; cat /proc/ioports | grep serial

    The ports seem to work correctly, though.
