I mean, we work also on imx53qsb board and we know that the last working kernel is
So, let's redefine the question: which is the latest working kernel for this board?

Thank you, but I'm still missing something.. I suppose that linux-imx is a patched version of the kernel.org one, that include the support the specific freescale (imx) boards. Isn't it?
If yes, then I should prefer linux-imx because the freescale device drivers should not be included in fslc kernel...
Another question, how I should compare the imx kernel with the fslc one using the evk board?

Sorry to ask you such stupid things, but I feel a bit confused...

Thank you
