Hi 1. Is it possible to load an initrd from initramfs ? How would you do this if the initramfs is being loaded dynamically in the kernel (ie having the initramfs as initrd ) Because in this case, you will say root = /dev/initrd and specify 'initrd' as your 'initramfs source file' How will you specify the second initrd source? Thanks Rachita.

...ysroot/initrd) failed: 2 umount /initrd/proc failed: 2 Kernel panic - not syscing: Attempted to kill init! 2. This issue is irrespective of issue 1. I was wondering how I would be spawning the real init after the real_root_dev has been mounted.... In the normal booting case(i.e. without initramfs) prepare_namespace() returns and /sbin/init is executed in init/main.c:init(). But, in the initramfs case, since prepare_namespace is not called, this needs to be done in my init application on initramfs. Klibc does not support threads. Am i right here? So when I 'exec' linuxrc after mounting initrd, it will...

Hi, I''m having some problems with getting the latest linux kernel and xen build working on ARM''s Fast Model simulator ( Cortex A15 ). I tried a lot of different configurations and I''m having trouble with all of them. I got all my information from the wiki pages at http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions#Building_Xen_on_ARM . I was hoping

Hi, I 'am trying to launch linux kernel 2.6.7 with initramfs. My pxelinux.cfg/default file looks as follows: default a1 prompt 1 timeout 600 label a1 kernel vmlinuz-2.6.7-1 append initrd=initramfs_data.cpio.gz root=/dev/ram0 init=/linuxrc Kernel image vmlinuz-2.6.7-1 and initramfs_data.cpio.gz was loaded succesfully by pxelinux. Kernel says: checking if image is initramfs... it is but

Hello, There seems to be problem in the cpio unpack in the kernel in initramfs. I have an empty "/sys" directory in my cpio archive, but it never shows up in my extracted initramfs. I've confirmed that extracting the archive again with cpio results in a correct tree, but it doesn't appear on boot when extracted by the kernel. Any ideas? I poked a bit, but I haven't

I think the main bit of the puzzle that's missing for klibc integration at this point, other than the kbuild bits, is a kinit that's a true replacement for prepare_namespace() and everything south of it in init/main.c. This means that it should be able to replace all that code and any code that's removed from it, totalling about 6000 lines of kernel code. The kinit that's currently in the klibc tree is missing quite a bit of functionality, such as proper...

...mat. However, I have some questions as too what exactly /init in a iniramfs system is responsible for? My current images probe/configure devices using devfs and libkudzu (basically, the same as knoppix detection setup) and create a tmpramfs root for use with pivot_root. However, looking thru prepare_namespace, it appears that MD arrays need to be detected/fired up as well as the root changed. Would my /init need to do something to startup MD arrays ? Can I still just mount devfs on /dev as I do in the initrd images or do I need to do some lower level setup first? I'd also LOVE the ability t...

I'm wondering where things are on the roadmap for klibc and initramfs/early userspace. When will everything be harmonized with the kernel and be the default? What is left to do? I'm in my own little world, but I have a pretty good klibc/hotplug/udev/kinit early userspace that just works (for me). It's taken me a bit to get things to work because I just couldn't find all the

Hey all, Just downloaded the new Xen 4.0 and ran Make xen Make tools Make stubdom Copied the new files from dist/install Im already running pv_ops 2.6.31.6 kernel. When I boot i get (XEN) Panic on CPU 0: (XEN) IO-APIC + timer doesn''t work! I have tried booting with noapic boot option but makes no difference. The system worked fine on 3.4.2 CPU is AMD.

Hi, The following set of patches is intended mostly to improve ipconfig and nfsmount compatibility with glibc. The context: I'm working on yaird, an alternative to mkinitrd, and currently implementing nfs root file systems. This is based on ipconfig and nfsmount from klibc, with a rewritten version of kinit. Users should be able to build the package with vanilla glibc, since klibc is not

Hi all I'm trying to boot with initramfs I build my own root fs, and the kernel build links it, I have double checked this when the kernel boots unpack_to_rootfs() returns no error, so it continues and .... when It tries to mount the rootfs it tries to mount from an IDE device (where the kernel was built from), and not from the initramfs "image" I think this is not documented

Hi everyone, I am working on a project whose goal is evaluating the performance of the vTPM Manager. For this project I am using Xen 4.1, Kernel 2.6.31.13 with Fedora11. I I finished all installation and configuration parts. Now I need to boot the system with Xen but while booting, it is freezing at the step "scrubbing free ram". What can be cause this problem and how can I figure it
