I gave this a spin on my Cubietruck. (I was running cap-sdio-irq before.)

Ran a few ping tests with a simple
"sudo ping -i 0.1 -I wlan0 -s 65500 192.168.1.1"
After a few runs I got

sunxi-mmc 1c12000.mmc: smc 1 err, cmd 53, RD SBE !!
sunxi-mmc 1c12000.mmc: data error, sending stop command
brcmfmac: brcmf_sdio_readframes: RXHEADER FAILED: -110

The chip is pretty much dead afterwards.

With cap-sdio-irq it doesn't happen so soon, but it does.
Without either, the response time is bad with packet losses,
but at least it doesn't die.

Is this the problem Arend (CC-ed) was looking into?
