Hey.
Unfortunately I only have a couple Buffalo boards and a Qnap, all
essentially the same chip.
Say, if you find the time, could you run it through strace and post the
full output? (strace -o /tmp/kwboot.log -s 256 -T ..).
Just see where it bails. Maybe it's some issue worth trying to hack
around.
Thanks,
Daniel
