Hi,
I tried to use fiasco without jdb. It works fine, but, at boot time, sigma0 issues an int 3. After some analysis, int 3 is generated by init_memory in init_mem_v2.cc. It calls fiasco_get_status_phys(). If I comment this, everything is then fine. Why this call is for ?
Regards Marc

This call should return the physical address of the trace buffer status structure. Commenting this out is no problem.
