Thanks for the kernel images, Willy.  I'm still experimenting but
initial results are strange: I haven't seen a crash from the -ethan
image you provided, nor by a kernel with that config that I built
myself.  The config is only different from my crashing config by a few
options.  So perhaps some combination of options prevents the crash.
I'll see if I can narrow it down.

For a moment I thought I found a likely culprit: all along I've been
loading my kernel in to 0x02000000 in uboot, while the stock uboot env
(and Willy) uses 0x6400000.  But I've seen at least one
__rcu_read_lock oops since switching to 0x6400000.  So I guess I can
rule that out.

Thanks,

Ethan
