This can be easily reproduced on a running VM with the command: sudo dmraid -r -c
Bisection shows that this regression was introduced with: ca18d6f769d22e931d3ba1e8d1ae81953547a417 is the first bad commit commit ca18d6f769d22e931d3ba1e8d1ae81953547a417 Author: Bart Van Assche <[email protected]> Date: Tue Jun 20 11:15:41 2017 -0700 block: Make most scsi_req_init() calls implicit Instead of explicitly calling scsi_req_init() after blk_get_request(), call that function from inside blk_get_request(). Add an .initialize_rq_fn() callback function to the block drivers that need it. Merge the IDE .init_rq_fn() function into .initialize_rq_fn() because it is too small to keep it as a separate function. Keep the scsi_req_init() call in ide_prep_sense() because it follows a blk_rq_init() call.
