there are several things we can do. you can pick whicever you like. first of all, there are some things you might to know. it's true that the problem is known but we never know what caused it. we know that:
1. it affect intel chip
2. it happened with pstate driver
3. it happened on swapless (i.e : no swap partition) system
4. it happened when the ram free space is low
I have this problem on several occasion but each of them have different way fix. the possible solution would be:
1. we can start by installing irqbalance. it should balance the system load and make the system more stable.
2. disable pstate driver. you can do it by adding "intel_pstate=disable" on your boot parameter.
3. reduce kernel swappiness. you can do it by editing the sysctl.conf file.
Code: Select all
AFAIK directly using echo command won't work. you need either root access or use sysctl to correctly do that.
4. install liquorix kernel.
5. regularly clear mem cache. "sysctl -w vm.drop_caches = 3". it's the same principle with sysctl but it used for single parameter.
6. replace the cooler paste on your cpu.
7. install tlp and throttling down the cpu. it's lil bit long and complicated so I'll explain later if none of these thing works.
these things are ordered by difficulties. you can start from top and continue one by one till the bottom.
