udev at boot

[Lucio Crusca <lucio@sulweb.org>]

Hello *,

I'm fighting with a problem that comes up sometimes at reboot with Etch.
Sometimes the system hangs on the message:

"Waiting for /dev to be fully populated..."

but some other times it works and the boot process continues normally.

Searching with google I could realize this is related to udev, but I don't
know how to debug what udev does at that early stage. I'd need to figure
out what's the udev child process that never finishes or, alternatively,
what piece of hardware udev can't initialize.

Do you know if there are any boot parameters to pass to udev in order to
have a detailed output if what's going on there?

Thanks in advance,
Lucio.
