I am very new to Linux. Ubuntu would freeze so I installed Xubuntu. That would freeze less frequently, but still so. Now, I am on Lubuntu, and it still freezes although least frequently. My system is a Lenovo Thinkpad 11e. Celeron N2940 @ 1.83GHz and 8GB.

The computer freezes in day to day tasks: watching videos, browsing the web, etc. Also, the default word editor was AbiWord. I started a document on AbiWord and saved it. But after my computer froze and I restarted it, it was not able to open that document.

This is almost certainly due to a bug in the kernel with some Atom-based processors. The workaround is to restrict the machine from going into deeper c-states.

Add intel_idle.max_cstate=1 to the kernel arguments by editing /etc/default/grub and set GRUB_CMDLINE_LINUX_DEFAULT so it looks something like this:

GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=1"

then run 

sudo update-grub

More details and the ongoing search for the root cause can be found in the issue at: https://bugzilla.kernel.org/show_bug.cgi?id=109051
