<div class="moz-cite-prefix">I recently got the same problem on a
regular machine, booting Barrelfish. The problem occurs when the
Barrelfish kernel is trying to add a large area of memory to the
memory-handover CNode (supercn) of the init process.<br>
<br>
I am not sure whether this has been introduced as a bug in a
recent release or whether it's always been there. Making the CNode
and associated data structures larger is an obvious workaround,
but it should be investigated first, whether there is something
wrong with the way capabilities are created for large memory
regions.<br>

<pre wrap="">Hi,
I'm having trouble with segfault below at boot under Simics.
Same image file works fine under Qemu.
