Jones (rjones@...hat.com) --- I think I have bisected this to: commit af2814149883e2c1851866ea2afcd8eadc040f79 Author: Christoph Hellwig <hch@....de> Date: Mon Jun 17 08:04:38 2024 +0200 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.
