I'm experimenting with baytrail cpu, and every 2 hours the system freezes. I googled and it says I have to implement intel_idle.max_cstate=1 or intel_idle.max_cstate=2. I have NOOOOO idea how to. Like NOOO idea!
I'd like line by line details. what I found is for Amazon linux and it doesn't work.
I have a partition /boot/efi if it makes any difference.
That's all so far
Thank you!
grubby --update-kernel=ALL --args=intel_idle.max_cstate=1
You can temporarily add kernel boot options pressing 'e' while grub menu is displayed
NOTE : see @Cosmin post
Thanks fcomida.
this is how I made it work after I googled a ton:
installed Grub Customizer
then, General settings>Kernel Parameters> [paste] intel_idle.max_cstate=1
then, Save and reboot
so far I've been playing shows on line and watched MP4s with no freezes
You did the same as what @fcomida suggested. You just went another way to come to the same result...
I believe the canonical approach for rewriting the current and all subsequent kernel updates is to edit /etc/default/grub and append the new parameters to the GRUB_CMDLINE_LINUX variable, for example,
GRUB_CMDLINE_LINUX="rhgb quiet drm.debug=0 drm.vblankoffdelay=1 intel_idle.max_cstate=1"
After that update grub as usual, the following bash script will help if you don't know if you're running EFI or not,
#!/bin/bash
cfg=grub.cfg
if [ -d /boot/efi/EFI/fedora ]; then
cfg="/boot/efi/EFI/fedora"
elif [ -d /boot/grub2 ]; then
cfg="/boot/grub2"
else
echo "Error: grub.cfg not found"
exit 1
fi
cfg="${cfg}/grub.cfg"
echo Backup $cfg
cp -pv $cfg /var/tmp
echo grub2-mkconfig -o "$cfg"
grub2-mkconfig -o "$cfg"
