I've attached the kernel log with NVMEM enabled and disabled for reference.

The NVMEM_BRCM_NVRAM driver won't work properly with NVRAM in NAND. It
causes the devices with NVRAM in NAND, such as ASUS RT-AC88U, to bootloop.
Until the driver is fixed, disable it.
Disable NVMEM too as the bgmac_bcma driver will hang trying to retrieve the
MAC address without NVMEM_BRCM_NVRAM enabled.
