The bug is affecting me too, after the upgrade to Intrepid. I had no problems before.
The boot is hanging about 1 minute on "configuring network interfaces" and is not possible to interrupt the procedure.
I attach the dmesg logs. The hanging is visible after about 22 seconds in the file timestamp.

My system is: Linux nittux 2.6.27-11-generic #1 SMP Thu Jan 15 11:42:36 UTC 2009 x86_64 GNU/Linux
On a HP pavilion dv6915nr laptop

This other bug report looks pretty similar: https://bugs.launchpad.net/bugs/295100

A workaround that worked for me was to comment the following two lines on the file /etc/network/interfaces

#iface eth0 inet dhcp

#auto eth0

I cannot check if this disables the lan interface because I'm using only a wireless connection.
I found this workaround reading about the bug #108152.

the notebook is my sister, she's using it on university network, but now she is in home

[nitto (nitto)]

If commented:
#iface eth0 inet dhcp
#auto eth0

The system does not recognize the wired connection.
So, if I want to use the cable I need to un-comment the two rows.
If I want not to hang at boot without the plugged ethernet cable I need to comment them...

Any idea???

so in order to use network-manager you need to remove all config from /etc/network/interfaces.

if it doesnt work, please reproduce and attach your complete syslog.

Well... if I remove all config about eth0 in /etc/network/interfaces, the network-manager applet in gnome says: Device is unmanaged under wired network. But the Ethernet network works perfectly.
Using ifconfig the eth0 interface is well configured (right IP address and default gateway).

If I leave all concerning eth0 in /etc/network/interfaces, the network-manager applet seems to work for the wired network, it gets the DHCP infos (apparently) but the network does not work at all.
Using ifconfig the eth0 interface seems not to be configured (the IP address is missing as well as the default gateway).

Which syslog can be useful? Let me know
