Were both of these kernels installed with a corresponding correctly functioning initramfs, which had all the requisite files (including -- firmware) to boot with, or only one of them did? Without an initramfs you will need to specify and build any requisite firmware blobs in the kernel image itself, so they are available to the system as it boots up.
