Recently I fresh-installed Gentoo 2006.1 (since then used 2006.0 or older), since then, I get "Letting udev process events" message upon booting, and it halts there some time and fails there. Somehow I have no other problem.

So I wonder what's "Letting udev process events" and how can I pass it successfully?

Thanks in advance.

udevd is started and gets events from the kernel: these events are sent by the kernel when it finds a peripheral like a hard disk or something plugged into a USB port. udev then goes through its rules looking for the action to take — create /dev/hda1, for instance.

If it fails there then it should have written an error message into /var/log/messages which you can post.

If your /dev directory is empty or missing /dev/console, however, it may not be able to even do that.

The minimum you need in your /dev directory as created on installation from the install CD is
Code:
crw------- 1 root tty  5, 1 Oct 22  2000 console
crw-rw-rw- 1 root root 1, 3 Oct 22  2000 null
crw-rw-rw- 1 root root 1, 9 Oct 22  2000 urandom
crw-rw-rw- 1 root root 1, 5 Oct 22  2000 zero

Thank you for your explanation. I have 4 devices you mentioned, so it's not a factor. But I have more serious problem. I don't have /var/log/messages. What am I missing? I've never experienced this before. (btw I have installed syslog-ng)

EDIT: oops. I forgot to start syslog-ng. I fresh-installed current gentoo yesterday.

It may be that syslog-ng, which is in in the default runlevel, hasn't yet been started. /var/log/dmesg may be there but it will only show the messages up to where init starts — and it is after this that udevd starts.

If your /dev directory, as installed, is OK — if you used the minimal install CD then it should have come from the stage3 you downloaded — then all I can think of is running /sbin/udevstart after booting up from the install CD and chroot'ng.

You have networking enabled, don't you? It's needed for the kernel and udevd to communicate using the netlink protocol.

Now I started syslog-ng in the boot level(should it be in the default level?), delete /var/log/messages, reboot, and am looking at /var/log/messages. But it's too long and I don't know where to look at. There are a lot of "class_uevent -".... and "class_device_create_uevent called for ....". Do they matter?

I don't know where to copy&paste here, so I uploaded on a http server messages so anyone can see everything. If possible will anyone point where it is wrong?

EDIT: Since I have nothing wrong with it, I should not mind it....in a way.

As far as I can see it's OK — you've even got a user, 'tetsuji', logging in and performing a successful "su".

There's no udev error that I can see.

There are two failed authentication messages from webmin which appears to start on the third try.

The only error message comes from gnome-power-manager which won't start unless dbus is started and it then advises that, after starting it, the machine is rebooted.

Thank you for analysis.

Yes, webmin authentication fails twice every time. But webmin itself works fine, so I don't mind.

Moved from Installing Gentoo to Other Things Gentoo.
not about getting gentoo installed, so moved here.
