Hello, since mainline kernel 4.19 LPAE is no longer working for me and some others on tegra124-nyan-big. Is this a known problem with a fix already available? The defconfig to compile the kernel can be found here: https://github.com/reey/PKGBUILDs/blob/master/core/linux-nyan/nyan-big_defconfig Basically we are only getting 2 GB instead of 4 GB of memory. Kernel 4.18 still gives us 4 GB. Both kernels are configured with CONFIG_ARM_LPAE=y. All newer kernel versions also have this bug.. Thanks, Tristan Bastian
