[qemu]Stay black screen!I think this phenomenon from kernel's config file
when I use qemu to simulate 3.10.88 kernel on my debian9.6,there is nothing on my compute(At least it should give me something-_-).There are some information about my works.
Information
1.qemu's parameter
qemu-system-x86_64
-m 1G
-kernel ./bzImage
-hda ./amd64.ext2
-nographic
-append "root=/dev/sda init=/sbin/init console=ttyS0"
2.The config that I used is x86_64_defconfig
3.picture
question:
1.when I used the kernel,same as the configure of the qemu,it is work well.
2.I extracted the config file from linux-image-3.10.0-1-generic_3.10.0.8_amd64.deb.I am going to compare between config-3.10.0-1-generic and x86_64_defconfig.compare result
and I add some options in x86_64_defconfig from config-3.10.0-1-generic.
3.Is there a general way to solve such problems?（I can't see anything here）
Thanks!
supplement
I add information from config-3.10.0-1-generic into x86_64_config,but it's not work.So I use GDB to debug.And I find kernel seems to stop at this place:(Sure ,I type Ctrl+C 2000 years later)
arch/x86/kernel/head_64.S
So,I initially thought it was stuck here.Is it going to be the problem?
