Subject: next-20160314 - crash in i2c_dev_init/bus_register_notifier at boot
Date: Thu, 17 Mar 2016 10:59:51 -0400 [thread overview]

Seeing this consistent crash on next-20160314. Sorry for shortened traceback,
hand-transcribed as the crash doesn't get logged to /sys/fs/pstore as
expected. next-20160307 works just fine.
BUG: unable to handle kernel NULL pointer dereference at 000000000260
IP: blocking_notifier_chain_register+0x37/0xd0
...
Call Trace:
bus_register_notifier+0x1c/0x20
i2c_dev_init+0x9c/0xf2
do_one_initcall_+0x99/0x210
? set_debug_rodata+0x12/0x12
kernel_init_freeable+0x1b3/0x240
kernel_init+0x3/0x100
'git blame' doesn't seem to find anything relevant and recent in
kernel/notifier.c or drivers/i2c/i2c-dev.c. Does this ring any
bells, or is it time to bisect?
