Hi Alex, That commit will have potentially changed the invocation number for mapping a page. Can you double check that you are using the new version of the generated headers from libsel4 and are fully rebuilding your user space with them?

We bisected the commits between 3.1.0 and 3.2.0 and [0] is the first bad commit for us. If we use the 3.2.0 release with [0] reverted on top than everything works as before - so no changes to Genode/seL4 as used for the 3.1.0 kernel are necessary. It's a know issue, or maybe something changed which must be adjusted in userland/roottask ? Thanks, Alex.
