I think the early printk stuff was stopping me seeing the message ....
Unfortunately, I found the conflicting driver, the 7846 touchscreen
driver, and disabled it, so the kernel boots again. (Before I could boot
with debugging messages enabled)
I suspect the kernel should not crash if two drivers try to claim the
spi device. If someone is interested, I can reanable the bad
configuration and try to collect better data.
