Wild guess: you recompiled with CONFIG_PREEMPT enabled.

I did.  It turns out it was CONFIG_REGPARM=y that is the problem (I
reported this to the list but since it has subscribe only b0rkedness
it's not appeared yet).

Great! Nice to know, thanks :-)

Right now I'm running with CONFIG_PREEMPT=y and don't see any
problems.  Is this purely luck right now.

I don't know if PREEMPT causes some setups to oops, it was just a guess because many bugs are inflated by that option.
