I've been working on getting my Mirabox running with the mainline
kernel.  There seems to be a problem with DMA and the mvsdio driver,
which causes the exact same dmesg for me.  Try loading the mvsdio
driver like so: "modprobe mvsdio nodma=1" and then modprobe the
mwifiex_sdio driver and see if it works for you too.
