    block: freeze the queue in queue_attr_store

    queue_attr_store updates attributes used to control generating I/O, and
    can cause malformed bios if changed with I/O in flight.  Freeze the queue
    in common code instead of adding it to almost every attribute.

Curious, does your init scripts attempt to load a modular scheduler
for your root drive?
