Linux On A Toshiba Click Mini...

[Paul Mansfield]

I started again from scratch with kernel 4.3.4 and used the config
file from the Debian jessie-backports kernel, applied the baytrail
patches and built a fresh 4.3.4 32 bit kernel, then built the Realtek
SDIO wifi driver.

Unfortunately the moment I load the driver it causes a continuous
flood of the following messages and the TCM collapses

Before I installed the driver, it seemed to be running fine :-/

It should be OK with a Ralink USB wifi module, the kind often used
with Raspberry Pi.

In case anyone wants to play, I uploaded the kernel and driver to the
usual place
