+The old vendor U-Boot 2017.09 did not leave enough room between the kernel and initrd, causing recent kernels to overwrite the beginning of the initrd. This can be fixed by increasing <code>ramdisk_addr_r</code> in the U-Boot console, or using upstream U-Boot.
+Here is how to achieve in the uboot console (hit enter during boot to access it):
+<syntaxHighlight>
+=> print ramdisk_addr_r # this prints the old value
+ramdisk_addr_r=0x06000000
+=> set ramdisk_addr_r 0x07000000 # this sets a new value
+=> saveenv # this persist the the configuration
+=> boot # than you can normally boot, if it still fails, you can try to increase the ramdisk_addr_r value further
