How long did it take?

The rest of the information is very helpful in narrowing things down,
but the result is strange: it looks like the hang happens on the
nominal code path (no prefetching etc.), despite the heavy sanity
checks there. I need to think about this...

There's just one more test that would be useful, if you get a chance:
unload tp_smapi+thinkpad_ec+hdaps, load the vanilla hdaps module (not
the one patched by tp_smapi) and see if this causes the hang:
# while true; do cat /sys/devices/platform/hdaps/position; done
