libertas sd8688 causes crashes/panics all the time

[Steinar Midtskogen]

Hello

As it has reported on this list before, the Guruplug crashes om wifi
client mode.  It can easily be reproduced after a few minutes/hours
with some network traffic.  I'm using ssh.  I've had the Guruplug for
nearly half a year and it's been like that all the time.

Why do I think libertas is the problem?  The crashes only happen in wifi
client mode and when there's wifi traffic.

Here's what's reported at boot:

[   36.395447] libertas_sdio: Libertas SDIO driver

Below are the kernel messages during wifi activity.  Please let me
know if I can give more info or test anything.
