Package: udev
Version: 175-3.1
Severity: important

Dear Maintainer,

ThinkPad W520 with NVidia Quadro 1000M usually hangs on boot at
"waiting for dev to be fully populated" when the discrete card is selected
in the BIOS.  When either the onboard card or NVidia Optimus is selected, the
system boots normally and the onboard card works fine. I do not know if it is a
udev problem or a kernel problem or what, I just guessed.

It hangs the same way when booting in recovery mode.

Once in a while it will boot with the discrete card selected, after which the
nvidia-glx driver works fine. This happened before I ever installed nvidia-glx.

Hmm.  I can't see where to move forward from here, so closing. :/
Also cc-ing the nvidia-glx maintainers for hints.

Thanks again, and sorry for the trouble.

Sincerely,
Jonathan
