[test] 82cced3b73: BUG: unable to handle kernel
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux.git 20160412-sysdata-v1
commit 82cced3b732e0833fd3ccb40237f9dbc0f378cec
Author: Luis R. Rodriguez <mcgrof(a)kernel.org>

test: add sysdata loader tester
This add a load tester for the new extensible sysdata
file loader, part firmware_class. The usermode helper
can be safely ignored here.
The sysdata API has two main interfaces, synchronous and
asynchronous, we provide 4 types of trigger tests for
each:
* trigger_request: sync simple loader
* trigger_request_keep: sync, asks for us to manage freeing sysdata
* trigger_request_opt: sync, the file is optional
* trigger_request_opt_default: sync, optional, try test-sysdata.bin
* trigger_async_request: async simple loader
* trigger_async_request_keep: async, asks us to manage freeing sysdata
* trigger_async_request_opt: async, the file is optional
* trigger_async_request_opt_default: async, optional, try test-sysdata.bin
