Bug#642571: NFS root no longer works with oldstable DHCP server
Package: linux-image-2.6.32-5-amd64
Version: 2.6.32-35squeeze2
On an NFS root boot with this version, the boot fails after reporting
"IP-Config: no response after __ seconds - giving up" once "__" reaches
100. It then outputs "/inet:...can't open '/tmp/net-*.conf'" and
"Kernel panic" etc. (Sorry, these message are from memory, since I'm
sending this from the machine that fails, and no logs get written.)
The old release still boots fine (though I'm using the newer modules for
now):
----------
$ uname -rvm
2.6.32-5-amd64 #1 SMP Wed May 18 23:13:22 UTC 2011 x86_64
----------
The DHCP server is dhcp3-server 3.1.1-6+lenny6. When the newer kernel
boots, it logs the DHCPDISCOVER/OFFER, but no DHCPREQUEST/ACK. There is
iptables firewalling on the DHCP server, but no blocked packets are
reported. Otherwise the server and client are directly connected.
Client boot options are:
----------
append root=/dev/nfs nfsroot=__.__.__.__:/___ ip=dhcp rw
----------
