Preconditions for this are:
- E100 card stopped working for some reason (no idea why, it just does sometimes at this oldish 2x P-III machine) - There are active datastreams running in and out (around 0.2 Mbps out, multiple megabits in.) - Commanding then "ifconfig eth0 down" results in what feels like system freezing, but it does recover in about 30-60 seconds (it takes long enough for me to sweat bullets...) - While in freeze state, keyboard can go crazy, but mouse does respond, as well as tvtime shows bt848 captured live video. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
