So, I see two different boot failures on the Peach Pi[t] Chromebooks: 1) next20141121 boot fails due snd-soc-snow Disabling CONFIG_SND_SOC_SNOW makes the boot to got a little further but still fails with the second issue: 2) next20141121 boot hangs if unused clocks are disabled. I tried to root cause these two issues but didn't see anything evident so I'll find a last known good commit and bisect. If anyone has an idea of the possible causes for these issues that would be appreciated. > Might I also suggest that folks have their default command-line to > *not* use clk_ignore_unused, since it's primary job is to workaround > clock bugs. > Agreed, I disabled now as well to catch regressions early. I carried those parameters from Snow since I needed clk_ignore_unused to have simplefb working on that machine. > Kevin > Best regards, Javier -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
