BUG: scheduling while atomic

[x427 at lavabit.com]

I just wanted to let you know that I'm experiencing the same problem on a
Zipit Z2 (PXA270 based device) running Linux 2.6.36-rc1.
The device is using a Libertas wireless chip connected via SPI.

As soon as there is some data transfer on the WLAN is see this message
printed over and over again:

BUG: scheduling while atomic: lbs_main/1570/0x00000002

After a short while, the WLAN stops working.
