 Posted: Sat Feb 11, 2006 2:07 pm Post subject: [**SOLVED**] Kernel panic - not syncing: No init found. |
 |
|
This is the same problem as found in https://forums.gentoo.org/viewtopic-p-3103202.html. I'm hoping there might be someone here who could shed light on the problem.
Whenever I attempt to boot a 2.6.15 kernel, I get the following output:
| Code: |
powernow-k8: Found 1 AMD Athlon 64/Opteron processors (version 1.50.4)
powernow-k8: BIOS error - no PSB or ACPI _PSS objects
ACPI wakeup devices:
PCI0 PS2K UARI AC97 USB1 USB2 USB3 USB4 EHCI PWRB SLPB
ACPI: (supports S0 S1 S3 S4 S5)
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Freeing unused kernel memory: 180k freed
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
|
I have also noticed that whenever I try passing an init= option to the kernel, through GRUB at start-up, there is an additional line that reads much like this, placed before the 'Kernel panic' line (assuming I have passed 'init=/sbin/init'):
| Code: |
Failed to execute /sbin/init. Trying defaults...
|
This is made more puzzling by the fact that I am able to boot a 2.6.12 kernel, on which I am currently running. I have udev set up and both my disk controller and my filesystem drivers are compiled into the kernel. I am currently running on a recompile of 2.6.12 (my third grub.conf entry) to ensure that my kernel configuration wasn't at fault, which it appears not to be.
Cheers,
Dan

Try to launch /bin/bash as init. When it fails (not with 'not found' error, but something like 'failed to execute') check whether you have compiled ELF support into kernel - you may have accidentially turned it off. I Guess, that if your binaries are in ELF format kernel without support for ELF will not be able to launch them.

Thanks smerf, that was exactly the problem. I'm feeling fairly stupid right now...
