More info: I tried to use tifm_core.c and tifm_71xx.c from 2.6.18-mm3
with 2.6.19-rc2-mm2 and the crash also happens.
Hope this helps.

After that the system behaves normally but hangs solid during suspend-to-disk.
This bug didn't happen with 2.6.18-mm3 (last kernel used).
dmesg (with another subsequent bug) and .config attached.
