I am able to confirm that @ih8lag has found the root cause of the long standing segfault bug on LePotato.
It was related to a patch in u-boot added by kszaq designed to speed up the boot process, I would never have thought to look in u-boot myself.
bootloader.img (656.5 KB)
Download the above file to /storage and execute the following commands to replace your bootloader.
dd if=/storage/bootloader.img of=/dev/mmcblk0 conv=fsync bs=1 count=112
dd if=/storage/bootloader.img of=/dev/mmcblk0 conv=fsync bs=512 skip=1 seek=1
There is no need to download and reflash the whole OS if you don’t want to.
