    i've been running BSD as a gateway on my old i486
    for a few years now and have just reconnected my
    modem (was on DSL). unfortunately there
    is a constant problem with sio buffer overflows.

    not surprising i hear you say as it's in the bugs
    section of sio(4).

    still, the system is running 5.0 release well and
    i'm reluctant to decomission it over something
    trivial. anyone ideas on how to tune to eliminate
    the overflows? failing that what version would i
    need to drop back to 4, 3? i don't remember the
    problem existing in late 4 (4.6-4.7) but cannot
    verify 100% at the moment.

    i've attached the dmesg output including errors
    from sio1@57600. the test was a simple -- tip to
    the modem and then ati4 to generate enough output
    for the overflow.

    thanks for any advice.
