** Description changed: Hi, I am running ubuntu 20.04 LTS on my laptop and have had this issue of the computer freezing ever since I installed this OS. When this occurs, I lose all control of my laptop, and nothing but a hard reset will fix the problem. I believe that this is related to the cstate issue that is most common in the intelbay trail processors (I've seen many forums discussing the same issue). This is because when I pass in the grub-boot-parameter GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=3, this issue never occurs. However, the issue has come up when I set - max_cstate=5; so I believe that the issue is caused when the processor - enters a cstate between 4 and 5. + max_cstate=5; so the issue is caused when the processor enters a cstate + between 4 and 5. - The downside of this workaround is the degradation of battery life (it - does not last for 1/4th the usual time). + The downside of this whole grub boot parameter workaround is that the + degradation of battery life is heavy reduced(it does not last for 1/4th + the usual time).
