>Description:
Using the nvidia driver with -current and clang seems to generate a kernel panic when the nvidia driver is loaded during the boot process.

If the driver is loaded after system boot, there is no panic or crash and the system works normally.
>How-To-Repeat:
Compile driver with default compiler (clang) and set the nvidia driver to load at boot time.
>Fix:
set USE_GCC=any in Makefile for the port.
