Kernel panic, hark lock on cpux

jeffwin2018

各位，请教个问题，我们基于Firefly 3308开发版自己做了一块板子，唯一区别就是使用了RK816 PMIC (Firefly的板子用的是离散IC)。核心硬件(CPU/RAM/eMMC/SDMMC/SDIO等）跟Firefly基本相同，软件上也是跟Firefly的配置基本相同，eMMC工作正常，但是1）Kernel启动后20多秒经常报Kernel panic （hard lock on cpux），2）有些时候会报PMIC的I2C总线中断未响应（rk3x-i2c ff040000.i2c: timeout, ipd: 0x10, state: 1），I2C降速但是还是会偶尔报这个错误。目前还不知道这两个问题的原因，希望各位高手帮忙解答。感谢！
