As I'm hunting around trying to figure out how to make exynos-drm work with v3.18 or linux-next, I noticed there was an exynos5-v3.18-rc2 branch in the exynos-reference tree[1], so I gave that a spin on my exynos5800-peach-pi. It seemed to work OK, but I noticed that as soon as the screen blanked after timeout, typing on the serial console would still work, but any typing on the keyboard caused a silent lockup, with no output on the serial console. I was able to easily reproduce this by doing # echo 3 > /sys/class/graphics/fb0/blank on the serial console, verifying I could still type on the serial console. Then, touch any key on the physical keyboard and then I can no longer type on the serial console, ping the target, etc. Kevin [1] https://github.com/exynos-reference/kernel.git -- 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
