Hi Mark, Lars-Peter,
I noticed the below panic on beaver (Tegra30). Seems like seaboard (Tegra20) is fine. This is with next-20130730, tegra_defconfig.
Hi,
So the same machine driver with the same codec works on tegra2, but not on tegra3? The crash doesn't seem to be directly related to the patch, but the patch changed the memory layout. Is it possible that you still have a outdated module that's being loaded on your tegra3 board?
Sorry, I should have been cleared on that. Not at all the same codec, seaboard uses wm8903, beaver rt5640.
Can you add a few debugging printks and run the test again and paste the last few lines before the crash:
