I am using BF532, 16M SDRAM and 4M nor flash on my board.
I used uClinux2006R2-RC2, when I access my fxs board, the err is:

make sure your driver isnt doing too much work in atomic context ... look at the code that is running where that small trace points you to

my driver access a register on my fxs board only. Some times the err occured, some times no. I think there are something wrong about my uClinux kernel, but I don't know where.
