@redroach - Thanks Matze for adding some more details - it's good to have as much information on how people are affected and on what hardware because this is an odd bug that isn't easy to reproduce, except seemingly with a few specific hardware combinations.

- My initial thought that it seems to be a 'Bay Trail Atom coupled with an SSD' problem has not held up. @cmeerw had a machine with the same N3540 processor as mine without an SSD and it had the same problem. I also managed to try a machine with an N2830 processor without an SSD and it had the same problem too using a Live USB. So why it works fine on a machine with an N2840 processor is peculiar.

- It might be worth trying the 4.14 kernel again without the intel_idle.max_cstate=1 in the grub configuration file, just to check whether the other odd behaviours might be due to that. Changing the cstate value will likely affect your battery life so it's not an ideal fix.

- There is a patch that has been written (by kernel.org developer Rafael) and Hai-Keng Feng has posted a kernel with the patch applied. Details in the next post... :)
