<p><b>New page</b></p><div>This page has a list of items which may be worth investigating in the future.<br />
<br />
If you see something that creates a long delay (e.g. over 250ms) then add it<br />
here and maybe some day we will try to investigate it.<br />
<br />
<br />
<br />
== netconsole extra delay for bogus network carrier detect ==<br />
Tim Bird saw this on the linux-tiny list:<br />
(see http://www.selenic.com/pipermail/linux-tiny/2004-August/000015.html)<br />
<br />
Network devices that say they've got carrier detect instantly at boot<br />
are assumed to have bogus carrier detect and netconsole waits a bit to<br />
assure the line is up and ready to go before proceeding. The timeout<br />
mentioned below could probably be shrunk.<br />
<br />
<br />
<pre><br />
>eth0: NE2000 found at 0x300, using IRQ 5.<br />
>> Universal TUN/TAP device driver 1.5 (C)1999-2002 Maxim Krasnyansky<br />
>> netconsole: device eth0 not up yet, forcing it<br />
>> eth0: driver changed get_stats after register<br />
>> netconsole: carrier detect appears flaky, waiting 10 seconds<br />
>> ^^^^^^^^---------this delay seems long<br />
