From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> commit eeaf06af6f87e1dba371fbe42674e6f963220b9c upstream. My patch caused kernel Oopses and delays in boot. Revert it. The problem was that I moved the "mem->dma = paddr;" before the call to be_fill_queue(). But the first thing that the be_fill_queue() function does is memset the whole struct to zero which overwrites the assignment.
