Title:
8k bcache cache NULL pointer deref on mount / can't boot
Status in linux package in Ubuntu:
Incomplete
Bug description:
After creating a bcache cache device with an 8k block size (see
#1662407), a kernel oops happens every time device is probed.
I'm not sure that there is any userspace bug present in #1662407 at
all - it may just be kernel. I've attached a dmesg there, but can't
actually get into the system at the moment to get apport-collect or
other diagnostics.
