[yocto] Kernel Panics on armv4t with gcc.4.5.1

[Kamble, Nitin A]

Diego,
  Can you try with 4.5.2 gcc from this branch: http://git.pokylinux.org/cgit/cgit.cgi/poky-contrib/log/?h=nitin/khem_gcc_nitin

Thanks,
Nitin

Subject: [yocto] Kernel Panics on armv4t with gcc.4.5.1

Folks,

I'm not a kernel and neither a gcc expert developer, and after searching for a solution for the last 2 weeks I've decided to appeal to the list.

I'm trying to build a kernel image (2.6.32 and 2.6.30) for mini2440 (armv4t) with Yocto Project (poky master branch) and I'm facing a strange issue.

If I compile the kernel with Yocto gcc recipes (gcc 4.5.1) the kernel will panic on init (console printed message is attached for kernel 2.6.30 and 2.6.32).
But, if I compile the kernel with meta-oe gcc recipes (gcc 4.5) everything will be ok.
Just for your reference these is the gcc recipes which I'm using:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-devtools/gcc
http://git.openembedded.org/cgit.cgi/meta-openembedded/tree/recipes-devtools/gcc


I've compiled with and without thumb instructions, but the issue remains.
I've tried to apply the patches gcc-armv4-pass-fix-v4bx-to-ld.patch and gcc-arm-volatile-bitfield-fix.patch, but no success.



Kind Regards,
