User-agent: | Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Thunderbird/24.0 |
gdb show that the statement that is excuted is 93 ret = nb->notifier_call(nb, val, v); and qemu just says "[0]kdb>" but i can't type a word in it. When I run : qemu-system-x86_64 -kernel /home/mm/kdb-work/bzImage -append "root=/dev/sda" -boot c -hda /home/mm/kdb-work/busybox.img -k en-us The qemu starts but it seems that there is a problem because it says "Kernel panic -not syncing:No init found" I want to know if this make the problem? Does any body can help me? Thanks a lot
