A few other things to report...

1. I don't think the phone is shutting down fully when I say "shutdown 
-h now" and then remove the USB cable, whereas the hw-validation kernel 
did.  Is it a known problem?  If not, is there something I can do to pin 
it down more precisely?

2. There are 5 lots of "Slab corruption" in my dmesg.  I've no idea 
what that is, but it doesn't sound good!  Here's the first:

[    0.176330] Slab corruption: size-32 start=ced512c0, len=32

3. Also dmesg has "INFO: suspicious RCU usage".  I think someone might 
have already reported this, but in case not, here it is:
