Title: Intel Powerclamp does not run
Post by: wysiwyg on October 08, 2016, 04:22:04 PM

Good afternoon all.  Has anyone seen a situation where after loading the kernel to RAM, the system chokes with the following:

...
Booting the kernel.
intel_powerclamp: Intel powerclamp does not run on family 6 model 23
Failed to execute /init (error -2)
Kernel panic - not syncing: No working init found.  Try passing init= option to
kernel. See Linux Documentation/init.txt for guidance.
Kernel Offset: disabled
Rebooting in 60 seconds..

The ramdisk image certainly has an /init and the /sbin/init points to busybox.  I've recently tried to use the core64 kernel instead of the corepure64 so that I have a larger variety of software (since the corepure64 repo lacks in comparison to the 32bit one).  Also, nothing has changed in the grub menu.lst aside from renaming which kernel to boot to.  I've tried Googling for this, but can't really find any helpful info...

Thanks,
Dave

The lack of /init is the error; the powerclamp message is unrelated.

Thanks for the reply curaga!  The /init script does exist.  Here's the 'ls' output from the image:

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable.  Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as.

As you can see, /init is there, /sbin/init is there, busybox has been compiled with the 'init' applet.  Any other ideas?

Error -2 means "file not found". edit: Make sure you have the correct modules in the initrd.

Thanks for the continued help curaga, I think it is an issue with mismatched binaries and modules.  Let me make sure, looking under http://tinycorelinux.net/7.x/x86/release/distribution_files/ I can see the a core.gz which is rootfs.gz + modules.gz right?  I don't see a core64.gz, which I suppose should be rootfs.gz + modules64.gz right?

Thanks,
Dave

I think what's happening is that the /init script is failing when it tries to start /sbin/init (which points to busybox), hence giving the 'missing init error'.  Something is mismatched in my fs.  I'll keep playing with it...

Hi wysiwyg,   You'll find pure x86_64 under "Other Ports"

hope you find what you need there

Hey coreplayer2, thanks for the tip!  I'm actually not looking for the corepure64, but rather the 64bit parts that allow both 32 and 64 bit software to run - which should be under the x86 area IIRC.

Hi

well I believe the x86_64 modules are the same, however from http://tinycorelinux.net/7.x/x86/release/distribution_files/ (http://tinycorelinux.net/7.x/x86/release/distribution_files/)  you'll need

rootfs.gz
modules64.gz
vmlinuz64

 ;)

I just checked the md5sum for the modules64.gz in both repo's and they are the same file. Thanks coreplayer2!

Thanks to you guys, it was an issue with mismatched parts.  I've gotten the system booting now!
