the box is fully usable after it has booted up and (as you can see it in the config i've uploaded) i've got every kernel debug option enabled, including lockdep. > Specifically, I'm wondering whether the net_rx_action softirq may be > scheduled while we're in poll_napi holding the poll_lock. > net_rx_action would try to take the poll_lock as well, and we'd be > hung for good. The patch with local_bh_disable/enable was supposed to > test that idea (this is the "trickle" patch) the box isnt hung - it just has no networking. (i couldnt get the logs out if it were hung - netconsole is the only remote debugging option and with that broken i can only get info out if it boots up fine) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
