For the archive and fyi answering to myself:

Here's my 'what it is not' list:

- madplay binaries and libraries are okay
- mp3 is okay
- playing over NFS is okay
- kernel config is okay

And now? Toolchain!

Compiling kernel with my old 3.4.1 gcc: madplay doesn't 
complain any more. Compiling kernel with my newer 4.1.0 with 
same config and same binaries: madplay fails. Haven't seen 
any other issues with my 4.1.0 yet, no error, failure, nothing.

Will see if I find time to investigate this further. Built 
my 4.1.0 with crosstool-0.42 and crosstool's

eval `cat arm.dat gcc-4.1.0-glibc-2.3.2.dat`  sh all.sh --notest

configuration.

Thanks for your help
