While trying to change the code of find_vm_area, I got an automated notification that my code was breaking the testing of i386, based on the 0-day testing automation from 01.org
I started investigating the issue and noticed that it seems to be reproducible also on top of plain 4.16-rc2, without any of my patches.
I'm still not 100% sure that I'm doing something sane, but I thought it might be good to share the finding.
The patch contains both a minimal change, to trigger the crash, and a snippet of the log of the crash i get.
