There is an issue with iasl on big endian machines: It
cannot disassemble acpi tables taken from little endian
machines, so we cannot check the expected tables.

Do not run iasl on those machines until this
problem is solved by the acpica community.

Is there an upstream bug report for this? It would be
nice to have a reference somewhere so we can tell if
we can remove the check in future...

thanks

Hi Peter,
I opened a bug http://bugs.acpica.org/show_bug.cgi?id=1082 and
started a discussion https://lists.acpica.org/pipermail/devel/2014-March/000637.html

Thanks,
Marcel
