[Solved] Udev hangs on boot after update

I don't know exactly what was updated that caused the problem, but udev hanged my computer whenever I tried to start it up. My solution consists of

hwdetect --modules >> rc.conf

from the live disk, and setting MOD_AUTOLOAD="no". But it's only temporary, and some modules aren't loaded properly because now my joysticks and USB sticks don't work. How can I find the problematic module and blacklist it so I can let udev do its thing again?

Re: [Solved] Udev hangs on boot after update

ok, can you be more specific: what do you intend with ''hangs on boot'' ?

have you check if in the bug tracker there are reported udev bugs ?

Re: [Solved] Udev hangs on boot after update

My computer boots up, udev says "starting udev uevents" (something like that) and my computer either crashes or reboots.

Searching udev on the bugtracker yielded no results. It may be a specific module loaded by udev but like I said, I don't know what it is.

Edit - I ended up fixing this by downgrading my kernel. Thank you.
