Seems nothing unusual.

The boot process continues just prior to the "INIT 2.86" line when the

although the panic  complains that  init  can  not be executed,  the problem
may not  be caused by init, make sure to pass the correct "root" arg to
kernel, which is your root partition, not the same "root" when you are in
grub's shell.

well, I assume these stuff is quite basic to you, but before I could see
what exactly your configuration is, this is all I could think about.
