https://bugzilla.kernel.org/show_bug.cgi?id=187051 --- Comment #11 from Hussam Al-Tayeb <me@xxxxxxxxxxxxx> --- At the time, the system was under very heavy load as I was compiling libreoffice and it was heavily swapping. I recently upgraded from linux 4.8.13 to 4.9.5 and then 4.9.6 I will do a Memtest86+ test to check if the issue is memory related. Thank you. -- You are receiving this mail because: You are watching the assignee of the bug.
