Hm, I hope I did not miss some info in the threads above, but have you tried to
use the config in /boot/ as a base for your new config with make oldconfig?
I think to remember make modules_install purges all existing modules under
kernel before installing the new ones. So likely there is something essential
going away when rebuilding the initrd. The messages sound like basic root fs is
not there, so it misses all the mount points. But I admit to be too lazy to walk
all the config.
