This is on an Alpha Miata platform (PWS 433au) with QLogic ISP1020 controller. Here's the implicated commit: edb854a3680bacc9ef9b91ec0c5ff6105886f6f3 is the first bad commit commit edb854a3680bacc9ef9b91ec0c5ff6105886f6f3 Author: Ming Lei <ming.lei@redhat.com> Date: Thu Jan 27 23:37:33 2022 +0800 scsi: core: Reallocate device's budget map on queue depth change We currently use ->cmd_per_lun as initial queue depth for setting up the budget_map. Martin Wilck reported that it is common for the queue_depth to be subsequently updated in slave_configure() based on detected hardware characteristics. As a result, for some drivers, the static host template settings for cmd_per_lun and can_queue won't actually get used in practice. And if the default values are used to allocate the budget_map, memory may be consumed unnecessarily. Fix the issue by reallocating the budget_map after ->slave_configure() returns. At that time the device queue_depth should accurately reflect what the hardware needs.
