Just a heads up if anybody is trying to reproduce this, it trashed my
ext3 rootfs, which is not recoverable.
Not sure what exactly caused this, but I didn't have anything like
this for a very long time.
I tried to reproduce the issue a few times more, and it crashed random
processes after the bug triggered, like mentioned above, and the box
never shut down cleanly.
It's entirely possible, that bug causes serious issues.
