That's the version I'm running as well, and I have no issues either. I think replacing the device tree (.dtb) at this point only helps with the onboard flash speed?

I've been running 6.12.9-current-rockchip64 for a bit more than a week after upgrading from 6.6.x, no issues so far besides the same issue with the status led service crashing. I'm running the 6.12.x dtb. $ ls /sys/class/leds/ helios64:blue:hdd-status helios64:blue:power-status helios64:green:status helios64:red:ata2-err helios64:red:ata4-err helios64:red:fault helios64:blue:net helios64:blue:usb3 helios64:red:ata1-err helios64:red:ata3-err helios64:red:ata5-err mmc1:: restarting to update to the latest 6.12.11-current-rockchip64, without replacing the dtb, I get the same output. md5sum /boot/dtb-6.12.9-current-rockchip64/rockchip/rk3399-kobol-helios64.dtb f4ca4834257ed410cbc53d994a251df0 /boot/dtb-6.12.9-current-rockchip64/rockchip/rk3399-kobol-helios64.dtb
