Hi, I'm trying to use device-tree on my at91sam9263 based board. Works so far, but I'm getting those BUGs for each SPI device being probed (2 in my case)
[ 2.787000] BUG: scheduling while atomic: spi32766/37/0x00000002

Currently, I can't figure out why this happens. It's a plain v3.14 kernel with
some own patches which don't affect SPI.
Best regards,
Alexander
