We are fighting sporadic segmentation fault and illegal instruction
crashes of standard shell commands like lsusb, lsmod, cp, du etc. on
a rootfs build with ptxdist and OSELAS-Toolchains. The problems seem
to disappear when we use a different Toolchain (ELDK).
I discovered similar problems on an AM37xx and OMAP35xx with Linux 3.4
and 3.3.
Any ideas of what could be wrong will be highly appreciated.
Did you try to activate all the Kernel Arm-Errata?
At least for OMAP3503D we figured out that it suffers from more than
what the Kernel-Doc says: https://lkml.org/lkml/2013/2/18/349
With all erratas enabled, the AM37xx was (in my opinion) more stable.
We also ruled out the kernel because running our kernel (build with
OSELAS-Toolchain) in an ELDK rootfs showed no problems.

I would love to understand what is causing these problems and would
highly appreciate any suggestion.
Yes, but you could try the errata and when they work, they may give you
a good hint what the real problem (maybe in the toolchain) is.
