    This is only true for the 18.09 release. 18.06 seems to work.

    If SoC revision is A1 or A2,
    You need to do one of these workaround:

    – Add an argument “cpuidle.off=1” to the kernel boot command line.
    – Update U-Boot to 2017.03-devel-18.08.0 or later.
    – Disable the kernel config “CONFIG_ARM_CPUIDLE”.
