Theories / workarounds (seL4)?
yes. Try to change the memory for Qemu in tool/run/power_on/qemu from 512M to something else, e.g. 511M. This workaround should help. We have seen this already some weeks ago and analyzed it. I turns out that the seL4 kernel memory management and the physical memory location of some ACPI tables collide in an unfortunate way. (seL4 kernel version 3.2.0 as used by Genode/seL4 in 17.05 release respectively on current master) Since we were already in progress of upgrading the used kernel to seL4 5.2.0, we decided not to fix it (by building a kernel patch against 3.2.0) With the update to seL4 kernel 5.2.0 (currently on staging for testing and scheduled for 17.08 release), the issue went away.
