I had this issue as well. I found a solution on stackexchange(..I think)
that I wanted to link here.. but can't seem to find it now. For reference, I
was using Ubuntu. This was my case:

* Possible reason - initrd.img file is too large
I checked the size of initrd.img-<kernel name> at /boot. The file was ~500mb,
much larger than the initrd for the kernel that came with Ubuntu(~40mb)

* Possible solution - 
Before installing the kernel, change  MODULES=most to MODULES=dep  in 
/etc/initramfs-tools/initramfs.conf to generate smaller initrd.img files.
The new initrd's for all other kernels I have installed afterwards have been
~55MB.
