I've had rootwait on for years. Other observations: If I boot the wheezy kernel with no initrd it hangs in rootwait for /dev/sda1. If I boot the wheezy kernel with initrd and no dtb it boots fine. If I boot the wheezy kernel with initrd and either the 3.16-2-kirkwood dtb (10037 octets) or the 3.2.0-4-kirkwood dtb (976 octets), it panics due to lack of root device just like with the jessie kernel. break=premount does not appear to do anything. 2102509 bytes read in 367 ms (5.5 MiB/s) 9907620 bytes read in 1111 ms (8.5 MiB/s) 10037 bytes read in 195 ms (49.8 KiB/s) ## Booting kernel from Legacy Image at 06400000 ...
