I'm sure you did mean "a known".
> benign issue when using KPTI kernel on Xen (see [1]). I still haven't found time to fix it and would appreciate help to solve the issue.
I've looked through the thread, and it seems it is not even decided how should it be fixed. Should it be a new interface, of fix would fit the existing, and the thread died pretty long ago.
On my side I just commented out that printk, because it renders a debug build unusable.
And I'm pretty sure Jairo is not up to fixing such XEN issues.
