When running OpenWrt on MT7623A, I receive a kernel
warning as follows (Device dts using mt7623.dtsi):
mtk-scpsys 10006000.scpsys: Failed to power on domain mfg
WARNING: CPU: 0 PID: 1 at drivers/soc/mediatek/mtk-scpsys.c:457 0xc04a4130
When I switch the device dts to using mt7623a.dtsi,
the system fails to boot:
rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:
rcu: 0-...0: (0 ticks this GP) idle=146/1/0x40000000 softirq=53/53 fqs=1051
(detected by 1, t=2102 jiffies, g=-1111, q=18)
Sending NMI from CPU 1 to CPUs 0:
Solved the problem by duplicating the power domain of
the MT7623 (except MFG) to MT7623A, the system works
fine without kernel warnings/errors.
