I try your kernel with kloader, it does not cause reboot.
(Maybe the primary kernel initialize all memories?)
When I boot it from CDROM, it reboots after probing g2bus,
but sometimes just hangs at the same point.

It would be caused some uninitilized memory, but
I don't think kthread code on dreamcast has problem
since kthread of atapibus0 is working fine anytime on my DC.
