Baytrail SDIO problems with linux kernel 4.7-rc3 (specifically Z3735F)

PMans — Sat, 18 Jun 2016 19:25:03 GMT

Hi,

I've been having problems with a Realtek R8723BS wifi device, which is SDIO, and kernel 4.7-rc3.

The symptom is that the device driver doesn't get to service the device's interrupts reliably. I get wildly varying ping latencies and eventually the network stack hangs, sometimes taking locking the kernel up too.

thanks for any thoughts

Paul
