Could be this a problem?: "imx-sdma imx35-sdma: firmware not found" appears when booting the kernel without enabled fb. In FB enabled kernel's the last debugable function is imx_add_platform_device_dmamask() Both have "dma" in the string... But for loading a firmware from filesystem, the kernel crashes to early, I think. If you subscribed to linux-fbdev mailing list, can you check If my message is come in there? Because marc.info archives does not show my messages on linux-fbdev, but all from other people after my message. I have send the message more times.
