Before I start digging in with GDB I want to see if this is expected or not.

Hello Myke,

Sorry for the delay - I've been on vacation.
Ubuntu on ARM comes with a compiler that doesn't generate the ARM specific unwind tables by default. I suspect you ran the libunwind testsuite against binaries that don't have any unwind infos (DWARF or ARM exidx). You may try to compile and run the testsuite like this:
make check CFLAGS="-funwind-tables"

There are still a lot of fails on ARM Linux and any help to get things further is greatly appreciated. The Linaro wiki has a page that focuses on libunwind on ARM and also shows some testsuite results at the end:
