kernel 3.2rc4 hangs if I use allyesconfig
Hi 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" If I use the config from a distro and create the kernel image, it boots fine.. 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.. For above testing, I used QEMU command as below
qemu-system-x86_64 -kernel /boot/vmlinuz-3.2.0 -initrd test.cpio.gz
Regards Rajaneesh PS: Config file has been created using allyesconfig, hence not attached..
Hi I was running the kernel 2.6.32 and 3.1.4... In kernel3.1.4, I could see additional messages below after the rootfs was getting loaded.. Refined TSC Clocksource calibration: 3214.622 MHz Switching to clocksource tsc.. My understanding was that kernel gets loaded completely before rootfs starts getting loaded.. The above messages were not getting printed in kernel 2.6.32.. Any thoughts on this? Regards Rajaneesh

Hi Rajanesh Could you post at least 20 lines of boot messages up to the time it hangs? The clue is quite too few IMHO. AFAIK, it already passed the decompressing of kernel image, so at least we know there is little chance kernel image got corrupted. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
Hi Mulyadi, Please find the screenshot...There are no debug messages being thrown out... Ran this from qemu with command qemu-system-x86_64 -kernel /boot/vmlinuz-3.2.0 -initrd initramfs.gz Regards Rajaneesh ----- Original Message ----- From: Mulyadi Santosa <mulyadi.santosa@gmail.com> To: rajaneesh acharya <rajaneeshacharya@indiatimes.com> Cc: kernelnewbies@kernelnewbies.org Sent: Sat, 10 Dec 2011 10:44:40 +0530 (IST) Subject: Re: kernel 3.2rc4 hangs if I use allyesconfig On 09/12/2011, rajaneesh acharya <rajaneeshacharya@indiatimes.com> wrote:
