[sisuite-users] Kernel panic on boot on DELL R720

[Pierre BLONDEAU]

Good After Noon,

We recently purchased a DELL R720.



So we tried with kernels 3.X after have patched si_prepareclient.

We tested a lot of combinations:
 - Kernel : 3.2, 3.8 and 3.11 ( lts ubuntu )

Network cards in this machine are too recent for our old kernel. It's a personalise ubuntu 2.6.32 with maximum of module. We had compiled the version 1.6.2 of the e1000e driver's . This version is too old for our machine. This kernel boot correctly, but the installation plant during the network configuration. - si_prepareclient patched by us or that present in the 4.3 beta on http://svn.oscar.openclustergroup.org/repos/unstable/

We also tried the kernel and initrd provided by systemimager-boot-amd64-standard: - 4.1.99.svn4556yaubert -> http://download.systemimager.org/debian/pool/main/s/systemimager/ - 4.3 -> http://svn.oscar.openclustergroup.org/repos/unstable/debian-7-x86_64/Early

At the begining, we have a kernel panic that looks like:
Freeing unused kernel memory: 532k freed
Failed to execute /init

See Linux Documentation/init.txt for guidance.

LABEL systemimager
    KERNEL u64/new/kernel
    APPEND initrd=u64/new/initrd.img root=/dev/ram ramdisk_size=1000000

Do you have an idea ?

Thanks in advance.

Kernel panic - not syncing: No init found. Try passing init= option to kernel. We tried disabling a maximum of kernel's arguments and increase the size of ramdisk in PXE's command line but it does not change :
