[ptxdist] Booting kernel crashes when using OSELAS.Toolchain-2014.12.1 for ARMv5TE

[Stranz Jan-Marc <JM.Stranz@gantner-instruments.com>]

Hi Juergen,

I also think it is hard to find out the root of the problem.
But  I have to find it out otherwise the new OSELAS-Toolchain isn't usable for our project and maybe also for others too.

I would underline the point again, that I didn't change the configuration of the bsp project (same kernel version, same versions of packages, ...).
I've only build a new cross toolchain with OSELAS.Toolchain-2014.12.1 and I use this toolchain to build the bsp project.

What can I do?
Would it help if I provide the boot messages?
I can also enable the "linux kernel early printk debugging" in order to get more information.
Is there any other think I can do to get additional useful information?

Best regards
Jan-Marc.

Hard to guess the root cause without more context.
