--- Comment #1 from Tanu Kaskinen <tanuk at iki.fi> ---
What do you mean when you say you ported pulseaudio to arm? Pulseaudio should
work on arm out-of-the-box.

After reading up on what SIGBUS might indicate, one possible cause for this
crash might be unaligned memory access. This will make alignment issues to
become invisible (with performance cost):

    echo 2 > /proc/cpu/alignment

Does that command appear to "fix" this crash? I hope it does, but in any case,
switch the alignment configuration back to 5 (or whatever was the original
value) and get a backtrace with gdb of the crash. A backtrace is needed for
further debugging.

You can read more about the kernel's alignment error handling configuration
here: https://www.kernel.org/doc/Documentation/arm/mem_alignment
