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

[Pierre B. <pie...@un...>]

Good After Noon,

We recently purchased a DELL R720.

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.

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 )
  - 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
Kernel panic - not syncing: No init found. Try passing init= option to 
kernel.
See Linux Documentation/init.txt for guidance.
Pid: 1, comm: swapper/0 Not tainted 3.7.5-boel_v4.3.0 #1
Call Trace:
  [<ffffffff8134bbb1>] panic+0xb6/0x1b5
  [<ffffffff81340640>] ? rest_init+0x70/0x70

  [<ffffffff8135192c>] ret_form_fork+0x7c/0xb0
  [<ffffffff81340640>] ? rest_init+0x70/0x70

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 :
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.

Regards
