PXE boot results in Kernel Panic

Hello!

I'm having an HP e-Vectra mini-computer that I wanted to install with the current Arch Linux iso.
Because USB-Installation failed (the computer did not recognize my stick!) and there is no CD-ROM, the only option I wanted to chose is install with PXE via network.

I followed the instructions at https://wiki.archlinux.org/index.php/Ar … pxe-server running this on my main Arch Linux machine, and on the first view all looked fine. On my e-Vectra, I first get a boot-screen and chose to boot into the Live System. The kernel begins to boot, and then stops with a Kernel Panic: Unable to mount root fs on unknown-block.

It seems that the kernel wants to mount a file system which is not there.

Do you have any ideas how I could solve this problem? It seems that there is no other way than installing it via PXE.

Any help would be appreciated! Thanks!

Re: PXE boot results in Kernel Panic

Please paste all error messages here, there are some incompatibilities between 2010.05 and current nbd pkg.

Are you running archiso-pxe-server inside installation media? The is the most recommendad way to avoid incompatibility things. Otherwise will require some hacks.

Other way is build yourself a more recent archiso.iso (just take few minutes), then  use my latest archiso-pxe-server script. This is tested at all at this time.

Re: PXE boot results in Kernel Panic

this is the message that comes up.

Well, my main system is Linux 2.6.36-ARCH #1 SMP PREEMPT Wed Nov 24 00:39:57 CET 2010 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ AuthenticAMD GNU/Linux.

Maybe I'll try the way running the PXE from a virtual machine.

Re: PXE boot results in Kernel Panic

Nothing interesting in the image, since relevant messages are above.

You can use new testing build isos from here: http://build.archlinux.org/isos/2010.12.18/ and use a newer aps script for these images from here: https://github.com/djgera/archiso-pxe-s … pxe-server

Re: PXE boot results in Kernel Panic

hi,

even those newest links do not work. I'm getting the same error.
Is there really now way to get this thing to run?

I don't have the time to get involved into archiso to build my own iso because I simply want to install arch linux on this single machine for only one time...

Re: PXE boot results in Kernel Panic

hi,

Hmm well I bootet now again with archiso-pxe-server version 20100925 and the NetInstall 05.2010 official Version of Arch Linux. The links you gave me yesterday did not work today (?), the client I want to install sais "No such filename", I think because it can't find a correct information.

Ok now with this version, on my Server I've run

./archiso-pxe-server -s /home/neo/Install/Linux/Distros/archlinux-2010.05-netinstall-i686.iso

without any errors.

The boot-commandline on the client then contains this:

/boot/vmlinuz26 initrd=/boot/archiso.img archisolabel=ARCH_201005 tmpfs_size=75% locale=en_US.UTF-8 ip=192.168.178.199:192.168.178.20:192.168.178.20:255.255.255.0 BOOTIF=01-00-01-02-02-a2-e7

I have to say that 192.168.178.20 is the IP of my server where I run archiso-pxe-server from.

Does this already help you to help me?
