Fiasco.OC won't boot on Aaeon FWS2360 ...

[Andreas Steinmetzler]

Hi,

in some experiments I'm trying to run Fiasco/L4re on a Aaeon FWS2360 
(https://www.aaeon.com/en/p/desktop-network-appliance-fws-2360) with an 
Intel Atom C3558. Unfortunately Fiasco gets stuck on boot when trying to 
start the different cores of the processor (I'm using the latest 
published l4re-snapshot-20.10.0). For this test I'm using the "hello 
world" ISO build with this command

     make E=hello grub2iso 
MODULE_SEARCH_PATH="${PWD}/../build-fiasco-amd64"

The ISO image boots fine on another amd64 system.  After adding some 
printf()'s to the file kernel_thread-ia32.cpp it looks to me that things 
get stuck with this call:

   // Send IPI-Sequency to startup the APs
   Apic::mp_startup(Cpu::boot_cpu(), Apic::APIC_IPI_OTHERS, tramp_page);

as it does not return anymore ... any hint how to debug this or drill 
down to get more information and the AtomC3558 system to boot?

Thanks

Andreas
