[Buildroot] kernel boot problem related to GCC ?

[Sagaert Johan]

Hi Thomas 

This is wat i tried :
Rootfs build in 2010.2 with kernel build with 2011.11 : fails
Rootfs build in 2011.11 with kernel build with 2010.02 : boots

So this showed that the boot problem is not in the generated rootfs.
(in fact i also tried other busybox version with the same result )

What i found in the build directory of the kernel was a file called .missing-syscalls.d, don't know if this has something to do with
it or not.

After finding no solution i ported all my patches i used on the 2.6.31.9 kernel to the 2.6.36.1 kernel and this works fine.

I have been building and building ...and i found out that building in 2011.11 with gcc 4.5.3 fails, using gcc 4.3.6 is OK !
Strange ...i think it might something to do with the ABI..
Gone try to do a build with gcc 4.4.x just out of curiosity.

Can you compare the versions of other packages used between both
buildroot versions?
For example, busybox probably changed version. Can you try stepping back that ?
