I am running into an issue I have never really run into in the past with my current laptop. Upon installing arch linux I reboot and face the following issue which hangs forever during the bot process: Waiting for UDev uevents to be processed [BUSY] I have a Lenovo Thinkpad W520 with NVidia Optimus and I enabled NVidia Discrete mode in the BIOS. I cannot boot into my system after installation, however sometimes it will skip by this error and I will lose all keyboard input and cannot login as a result. My workaround for the moment is to put the BIOS into Optimus mode (Intel and NVidia cards are enabled) and use the Intel video driver. I have tried nomodeset during the boot process but no luck. Googling the problem i find most people get a timeout after 30 seconds to find out what is causing the problem, but my system hangs forever. Is anyone else running into this issue or experienced enough to help me find out what the problem is? I have been running Arch since August 2011 with no issues up until now. Any help is appreciated, -Rob
