My recommendation for a first step is to look at your printk data. You didn't miss a flag, you're simply crapping out before the console is set up to dump out the printk data.
Go into the System.map file associated with the kernel your running, search for 'log_buf', subtract 0xc0000000 to get the physical addr of 'log_buf', hook up a BDI or something similar (and hopefully, your board has an appropriate connector), and dump the [printk] data at that address.
