Problem: Under certain I/O conditions, a program doing large block disk reads can cause a controller to crash. Root Cause: The SCSI read request and destination address in the BDMA descriptor is incorrect, causing the BDMA engine in the controller to assert. Fix: Change the alignment for creating bus_dma_tags in the driver from PAGE_SIZE (4k) to 1, which allows the controller to manage it's own address range for BDMA transactions. Risk: Medium Exposure: This reverts a change first made to support NVMe drives on Excalibur. At that time a 4k alignment was necessary. This no longer seems to be the case.
