klibc - Jan 2011 - ipconfig fails when an interface is flapping?

I had an odd situation yesterday, klibc 1.5.17 ipconfig was trying DHCP on
all 3 NICs in the server, but one has a bad switch that causes the link on
eth2 to go up/down every 10 seconds.  IPconfig would just time out.  If I
tell ipconfig to only try eth0, then DHCP address is configured, and the
netboot proceeds 100%.

I'll take a peek at the code but maybe someone here is familiar with the
behaviour already?

Hey Jeremy,

Can you confirm this behavior on the latest ? 1.5.21 ?

indeed 1.5.17 is a known bad ipconfig, is that an Ubuntu box?
use klibc >= 1.5.20, newer klibc packages install just fine on older
Ubuntu releases.

OK klibc-utils, libklibc from Maverick 1.5.20 works, thanks guys!
