Hi<br>
<br>
I created a kernel using the target as allyesconfig. The machine fails to bootup (just hangs with 100% cpu utilization) with message "Booting the kernel"<br>
If I use the config from a distro and create the kernel image, it boots fine..<br>
<br>
Apart from the fact that allyesconfig will create a bulky kernel image and loads lots of drivers that are not needed, what could be other reasons why this would fail.. I have 8GB RAM and AMD Quad code..<br>
<br>
For above testing, I used QEMU command as below<br>
>>qemu-system-x86_64 -kernel /boot/vmlinuz-3.2.0 -initrd test.cpio.gz<br>
