 99.393105] Code: a8c37bfd d65f03c0 d503201f f9420000 (f85d8000) 关于这个死机的问题现在有3种解决方法：第一种是在登陆系统后输入如下命令将CPU自动变频模式关闭
sudo systemctl disable ondemandpkill ondemand这种做法会使CPU不能自动变频，因此一直最高频率运行，增加了功耗，同时需要注意散热，但不会再不时死机第二种方法是进入uboot然后修改启动参数，首先使用手机数据线连接开发板和电脑，在设备管理器里面获取串口号

然后打开串口终端，选择Serial模式，输入上面串口号，波特率115200点打开

然后给开发板上电，不停按回车键直到进入下面uboot界面

输入下面命令修改启动参数
setenv bootcmd ‘mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name; mw.l 0xd0011500 0x78e3ffff; setenv bootargs $console root=/dev/mmcblk0p1 rw rootwait net.ifnames=0 biosdevname=0; booti $kernel_addr – $fdt_addr’然后输入下面命令保存saveenv接着输入下面命令启动进系统run bootmmc
第三种方法是使用Archlinux或者Armbian最新版固件
