I can't undestand the problem, I get the error (scheduling while
atomic) on two different systems with different architectures, one x86
and one mipsel.
Here a file with the click config and consequent errors.
Does anyone use successfully click in linuxmodule with kernel
2.6.19.2? With wireless devices?
Thanks for any help.
