Thank you. I'll be using this patch and report later what happens or doesn't.
Didn't help unfortunately. :( I can usually trigger the bug by using command stress --vm-keep -m N --vm-bytes 512m and trying out different values for N. It seems to crash soon if it does. My kernel is however not so vanilla anymore and I have been using patches from https://github.com/copperhead/linux-hardened and https://ck-hack.blogspot.lu.
