Hi,

Firstly, this problem has been ongoing since I dug my old laptop back to
life, say January 2018. I put a new SSD in before installing Ubuntu
17-10 plus updates. I later updated to 18-04, all at current latest
official releases.

I’m copying the full syslog output, since systems/journal failed.

I’ve also am copying the last run dmesg log as the kernel reported two problems:
(A) CPU stalled at around 40 seconds.
(B) Page protection error W+X.

I’ve removed the mainline kernel and reverted to current Ubuntu release.

Hope that helps.
