Ok, I got a little further now. And the problem is really strange, but maybe
someone is able to help.
I found out that the issue only happens if bios_ia32/start.cpp is compiled with
Clang. If I compile everything with Clang, but bios_ia32/start.cpp with GCC, it
works. It also works if I comile bios_ia32/start.cpp with Clang and disable SMP
or comment out the smp_init() line in start.cpp. However, smp_init() is defined
in another file which is compiled to Clang, so I guess this is not the issue
and something goes wrong before the call to smp_init(). I has to be something
in start.cpp, as it works when that file is compiled with GCC and all other
files with Clang. However, I can't figure out what goes wrong there when that
file is compiled with Clang.
