Hm, not an expert, but if you're a Qemu user, probably I can give you clue. When it hangs, go to Qemu monitor and type "print $pc" (if I recall correctly). It will print current executed instruction. And since your kernel hangs, it will point to the instruction when it hangs... or at least somewhere around that spot. regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
