Intel Bay Trail CPU C-states issue

Devices with Intel Bay Trail CPUs are affected by this bug which causes seemingly random crashes and has not been resolved so far. The only work around which has been reported to work consistently is setting the intel_idle.max_cstate=1 kernel parameter which has the drawback of increasing power consumption considerably.

/!\ During installation and until you have configured Grub as described below, you need to manually apply this parameter at each boot! Both in Grub and before launching the Debian installer, you can do this by pressing e after selecting the entry you want to boot and then adding the parameter at the end of the "linux..." line.

To set this parameter, edit the file /etc/default/grub and add the parameter at the GRUB_CMDLINE_LINUX line like this (if there already are other parameters there, leave them and just add yours at the end separated by a space):


then update grub with:

# update-grub
