So gcc-4.6.3, eglibc-2.13, from poky/denzil branch also failed, the same as the poky/master branch with gcc-4.6.3, eglibc-2.13. So I guess the I'll need to do a diff between the Denx ELDK 5.2.1 release, which is based on poky/denzil, and that of the current poky/denzil branch to see which recipes are different, and to try and isolate the cause of the kernel panics, when trying to run init=/bash/sh.

Hopefully, that comparison will yield some clues.


There are differences in eglibc.inc and initrd recipes. Try to see if they make difference
Also the libgcc one after the above two




I did a comparision betwen the poky/meta and the eldk/meta directories for the denzil branch. The ELDK one is roughly behind by around 2 updates to the denzil branch, I think.

One thing that I found, was the the ELDK install the no-float libraries for soft-floating point on the target, whereas the current poky/denzil branch does not:

Could this be the reason? Apart from the one above, here are all the other differences under recipes-core. Do let me know if any of them stand-out:
