That's looking good, at least you've already some initialization code
passed. The message "failed to communicate with thread event" might
imply that core triggered a pagefault, something which should never
happen normally, because virtual memory of core is translated eagerly,
and there is no pager resolving page-faults from core.

Please try to apply this patch to your branch:


https://github.com/skalk/genode/commit/89e296e3687b27a98d4cb1fa2787bf956feb5472

In case that core provokes a pagefault, you'll get additional
information about the faulting address and instruction pointer of core,
so that you can find out the root cause of the problem.

I think, it would be best to get this debugging helper into the mainline
repository.

The kernel is already started, even core, the first, and primary
user-land process, is already running. Now, you've to bumble through
arising problems.
