Belkin F5D8235 v1 (most likely all rt288x devices) are broken on Linux 4.14
Username: NotTheEvilOne
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=1511
For kernel 4.9 the router boots correctly but on 4.14 the following panic occurs:
[ 0.000000] Failed to request intc memory [ 0.000000] Kernel panic - not syncing: Failed to request resources for ralink,rt2880-sysc
Same happens when adding “syscon” to the compatible string.
