Hello out there,
after installing ubuntu on my new notebook yesterday evening, I encountered
the same problem: Hang while booting. Reading this and the corresponding Bug 28439 I found out that it also seemed to be the udev problem mentioned here.
0) Boot up with init=/bin/bash in the kernel arguments
1) Run "udevd --daemon"
2) Check that /dev/.udev/queue does NOT exist
3) Run "udevplug -s -v"
-> hangs for 3 minutes after "/sys/devices/pci0000:00"
4) Report the last line before it hands
5) Wait for up to three minutes, to see whether it times out and drops you back to the shell.
I really thought that must be a kernel problem, and if I would have gotten the network to run I would have compiled a 2.6.18er kernel to try it out.
So I commented out the /sbin/udevplug in /etc/init.d/udev to hopefully get network access ... but now the computer froze at the line "Configuring network interfaces".
Then I thought about, what fragile features of the kernel could be switched off?
Because ACPI support makes often problems with notebooks, I first tried that one.
And Bingo! No hanging, all is booting OK.
So now the only problem left is that I don't have the ACPI support for now.
But that isn't too bad for the moment, because I am able to really work with my notebook ;-)
Perhaps this simple solution will help others having this problem.
