Hi,
I'm working to implement the Linux Oprofile functionality on L4/Fiasco environment. OProfile configures the performance counter to raise a NMI whenever the counter overflows. I modified the NMI handling codes in handle_slow_trap() to collect samples but I encountered an strange system behavior, REBOOTING without any information. If there is no user application activity, the system looks fine. Otherwise, the system reboots even if a very simple application like hello runs and the required time before reboot varies. I don't know what causes this behavior. IMHO, it seems a kind of triple fault. Is there any one give me an advice?
Thanks in advance. -- Jugwan Eom
