it bootet fine with devfs, oh, and the config is the same since ages,
three days later, I switched to udev.
Btw, I greped the config for random/urandom, there was nothing found.
Hm, where should I look?
There's no Kconfig option because the random number generator is a
required feature. I don't see how it could be a udev issue because
the /dev/urandom device file is either there or not and after that
it's the kernel's responsibility. I would build a new kernel.

You can pretty quickly determine if it is a kernel problem or a udev
problem by adding a
'ls -l /dev/urandom' to /etc/init.d/urandom:
start() {
[...]
ls -l /dev/urandom # debug strangeness
ebegin Initializing random number generator
umask 077
dd if=/dev/urandom of=/var/run/random-seed count=1 /dev/null
Also, only the display options for devfs were removed from 2.6.12, the
code and config option in .config are still there. Can you double check
your kernel config, and make sure that # CONFIG_DEVFS_FS is not set.
I think if you copied an old kernel config, you could have devfs support
still in your kernel, which might cause some strange behavior. I'm not
sure.

I had devfs still in kernel, but no automount and gentoo=nodevfs in grub.conf.

Re: [gentoo-user] boot problem since devfs-udev switch
Hi, I switched from devfs to udev 10 days ago, and since then every nth boot will hang at 'initializing random number generator' It try to read a /dev/urandom, does this device node created properly by udev. In my box, there is corresponding rules in udev setting. Cheers, Zarick Lau -- gentoo-user@gentoo.org mailing list

[gentoo-user] boot problem since devfs-udev switch
Hi, I switched from devfs to udev 10 days ago, and since then every nth boot will hang at 'initializing random number generator' I had at least one udev-update since then, without changes. The box reacts to the sysrq-keys, so I am able to reboot - and the reboot is always successfull. I followed the udev-guide here: http://www.gentoo.org/doc/en/udev-guide.xml without the tarball, and the test mentioned there was succesfull (/dev/null and /dev/console were there). I googled a little bit, but found nothing. Has someone a clue, where to look? Glück Auf Volker -- gentoo-user@gentoo.org mailing list
