I installed Ubuntu 16.04 32 Bit Desktop (kernal - 4.15.0-29-generic) version in my machine (x64). And it freezes frequently. When I googled I found that this a Cstate defect in Kernal which happens in BayTrail processors.
I applied the following fixes, but it still freezes.
Changed the Max Cstate to 0 and also 1 and ran the command sudo update-grub (and restarted).Also tried different combinations of kernal boot parameters like:
GRUB_CMDLINE_LINUX_DEFAULT="quite splash intel_idle.max_cstate=1" GRUB_CMDLINE_LINUX_DEFAULT="quite splash acpi=force intel_idle.max_cstate=0"
Also tried the shell script - c6off+c7on.sh and made this as service, enabled it and rebooted.Got the following output when ran the command service cstatefix status. And I hope the service has run the shell script and exited or should this service keep on running? (I removed the cstate parameter in grub when I enabled this service)
● cstatefix.service - My Script Loaded: loaded (/etc/systemd/system/cstatefix.service; enabled; vendor preset Active: inactive (dead) since Mon 2019-01-28 13:43:54 IST; 51s ago Process: 824 ExecStart=/usr/bin/c6off+c7on.sh (code=exited, status=0/SUCCESS) Main PID: 824 (code=exited, status=0/SUCCESS)
Is there any other permanent fix for this issue?
If not what hardware (CPUs and Graphic card, and mother board) should I replace which will not be affected by this CState Issue.
Note:My Current processor is bit old - Intel core i3-370M with Intel HD Graphics.
