Rogério, thanks for doing all the work of bisecting. I know that's slow and painful. Can you please attach the complete dmesg log from a current upstream kernel with 12c22d6ef2 reverted? While you're at it, you might also try a boot of plain vanilla upstream with the "pci=use_crs" kernel option. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
