[SOLVED] UDEV hangs on boot

Hi, I just finished intalling a clean gentoo but when booting it seems that udev hangs just after this:

"waiting for uevents to be processed"

I know it's udev because if I don't initialize it, the system finishes booting.

One thing that bothers me is that after 10 seconds (more or less) the caret stops blinking.

I'm really lost and I don't know even where to look to see what's udev doing to get stuck.

it should be stuck while waiting for firmware loading to timeout.
have a look at https://forums.gentoo.org/viewtopic.php?p=7648414

I've seen that message but it happens with udev 216 and with eudev. What really bugs me is the caret stopping blinking.

hi,
do you probably have an older nvidia card and are using the proprietray nvidia-drivers package? I had this problem too, when I merged a version of nvidia-drivers which were to new for my card. (I also must admit, that I didn't pay too much attention to the news after the merge, which statet, that the version of nvidia-drivers was to new for my card.)
So after i downgraded to the correct version of nvidia-drivers, everything went along well.

also, for me, pressing Ctrl+C when the "waiting for uevents to be processed" canceled the process and the system bootet to login (I do not use any graphical login manager).

I have a Nvidia optimus double card, i'll try to remove the propietary drivers. About Ctrl+C, I have tried but didn't work.

You were right, I removed the nvidia drivers and it booted perfectly.

erzapito,

The Nvidia optimus is only a card and a half. The Nvidia half cannot refresh the display, hence its ontly a half a graphics card.
This is good for power consumption and price but bad for software complexity.

You must always usu the Intel graphics to refresh the display.

hi,
I'm glad, you could fix it. There is also a wiki [1] which describes, how to use nvidia optimus cards on gentoo. If this reference is not enough, you could also have a look at the corresponding arch wiki [2].

I've tried to setup it multiple times, but always got strange errors. Curenttly I'm pretty busy but I think I'll try to get it working again someday.
