高通6490之内核锁定规避异常

近期在测试一款6490的芯片主板的时候遇到了更新后设备无法上网的问题，最后排查发现是由于内核变动导致的，那就手动锁定内核来解决吧。具体方法如下：

1、先确认和排查当前内核

dpkg --list | grep linux-image
dpkg --list | grep linux-headers
dpkg --list | grep linux-modules

2、禁用自动更新

vi /etc/apt/apt.conf.d/10periodic
vi /etc/apt/apt.conf.d/20auto-upgrades

3、锁定内核更新

# apt-mark hold linux-image-5.15.0-92generic
linux-image-5.15.0-92-generic set on hold.
# apt-mark hold linux-headers-5.15.0-92-generic
linux-headers-5.15.0-92-generic set on hold.
# apt-mark hold linux-modules-extra-5.15.0-92-generic
linux-modules-extra-5.15.0-92-generic set on hold.

4、检查

sudo dpkg --get-selections | grep hold 

5、设置休眠

systemctl status sleep.target
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
