Hello!
BOARD: QuadMo747-X/T20
i get kernel 2.6.36.2 from nvidia tegra partners: Toradex Colibri (http://developer.toradex.com/software-resources/arm-family/linux/source-code/linux-(colibri-t20)-source-code), and SecoQseven (http://www.secoqseven.com/en/download/downloads.html)


I build kernel with option "User mode SPI device support"
Example of my board-harmony.c file in attachment

While 

echo -ne "x5c">/dev/spidev1.1 &  
kernel module interface spi freezes. (bash not responding, and ignore SIGKILL)
if i run spidev_test.c from Documentation/spi folder - process spidev_test freezes
