AN issue?

I wouldn't suggest that...

Are you by chance S-Off, or S-On? How long is "A while?" I had times where it took (literally) 15 minutes to restore the boot partition alone.

If you're S-On, I'd recommend fastbooting the kernel you need.

 

If its been there for like 20 minutes on the boot partition alone, then if you have the copy of the ROM or kernel, you can pull out the boot.img and do "fastboot flash boot.img" once your in directory containing the boot.img in cmd. The second option is to battery pull, hold power and volume down, go into boot loader, go into recovery, restore backup again. If the restore freezes again, do the same thing in option except when you go into recovery fresh(wipe everything) install the ROM and restore only data.

 

You must be S-ON, so another option is to start TWRP recovery using the following fastboot command:

fastboot boot twrp_recovery_file_name.img

That will boot TWRP recovery in a mode that will allow it to flash the boot partition, then you can just run the restore again from there.

I just noticed that his problem do seem like he's s-on
