That stuff went in in time for 2.6.29-rc2, so it's unlikely to be the cause of your problems. > I just want to ask who is working with the au1550 on a more recent > kernel than 2.6.16.11. > I'll start now with some early printk to solve booting problems and than > we will see ..... I know of at least one person running 2.6.26 or .27 on a Au1550. You should start by throwing away the defconfig ;-). Create a new config with only au1x00 serial and serial console enabled and then add new devices one at a time and see where it breaks. (Btw, which board? I'd love to get my hands on other alchemy boards to test on). Thanks! Manuel Lauss
