--- Comment #3 from Harry Wentland harry.wentland@amd.com --- The warnings are likely not related to the hang in this case.
Installing or building the kernel might depend on your distribution. You should be able to find a guide by googling "building a custom kernel <distroname>".
In general you might want to * mkdir mybuilddir * git clone git://people.freedesktop.org/~agd5f/linux * cd linux * cp /boot/config-<your-current-config> .config * if you're on ubuntu/debian: * make deb-pkg * sudo dpkg -i <path to custom kernel .deb from your install>
