I am using the latest available, 2.1.1-patch.9

Platform ... well that's the thing, I am trying to make it running on
UltraSPARC.

I didn't make any changes other than making stuff in
libs/c/include/stdlib.h __builtin which should not be an issue here. I
have all my platform/architecture specific stuff in arch/ platform/
subdirectories.

I am compiling with gcc and CONFIG_VERBOSE_INIT enabled.

Just for the record, on line 732 in pistachio/src/scheduler.cc just
after init_root_servers() the call to get_current_tcb() should return
the tcb of the idle thread or the rootserver? I was thinking about it
a bit more, I am returning the rootserver which is probably the
problem, right?

Cheers, T.
