Linux kernel



  • Most official kernels shipped with fog could not reboot in my PCs. The only working version is 3.17.3, but has a kind of USB error. So I want to build the kernel by myself. Is there any thing need to aware? I think all modules shall be compiled into bzImage, right? Anything else?



  • @Sebastian-Roth Thanks for the kernel, but it doesn’t work too. There is no error message, just stopped at the last step of regular reboot/shutdown process. The last step should be a signal to hardware. I uploaded a picture of the screen here. https://drive.google.com/open?id=0Bx_soHaLoSYETllpSUVmVEotX28 So the kernel config may do the trick.



  • @Quazz Windows & Ubuntu 16 could reboot/shutdown. And there is no BIOS update.


  • Developer

    @Maorui2k Ok, to see if the Ubuntu patches do the trick I downloaded those, applied to a vanilla 4.4.0 kernel, used our FOG kernel config and build a kernel from that. Please download bzImage and init.xz here. If this kernel properly shuts down your machine then we can start looking through the patchset. On the other hand, it this kernel does not shutdown/turn off your machine, then the Ubuntu patches are irrelevant and you can start comparing the kernel configs and/or parameters.

    @Maorui2k said in Linux kernel:

    I tried CentOS 6 & 7, both have the issue. So Ubuntu is the only survivor. I’m still finghting with the Ubuntu kernel compile process. It’s not same as general process, and I always got error in the middle. Not sure the reason yet…

    Please post the error so I might be able to help. Without I don’t have a chance to give you a hint. Let me know which steps/command you do/run and which error you get.

    I am wondering if it’s Ubuntu’s kernel config or if they have a special patch that does help shutting down your machines. The problem is that building a normal Ubuntu kernel won’t help you because FOG has all the important drivers included in the kernel (bzImage) while Ubuntu has most in the initrd. Ubuntu kernel is smaller but would not work with FOG (initrd). I’ll think about it a little more and try some stuff.

    @Maorui2k If you have an operating system installed on them, can they shut down/reboot?

    Are there any BIOS updates available for this motherboard?



  • @Quazz I tried debug mode, both reboot & shutdown had same result. I could see the message of killall process, but the PC just hung there after message ‘Requesting system reboot/halt’, and the keyboard was freezed too, CTRL-ALT-DEL won’t work.


  • Moderator

    @Maorui2k “same result” being nothing happening at all?



  • @Quazz I tried and got same result.


  • Moderator

    Can you try to boot one of the machines in debug mode and try to reboot there?

    It’s unlikely, but perhaps it will give some useful information.

    I’m guessing these are custom built PCs? (given that no DMI info is supplied)

    It’s interesting that under certain circumstances they wouldn’t reboot.

    What about shutdown? Does that work?

  • Developer

    @Maorui2k Sorry for not getting back on to this. Did you get to build your own kernel and find/fix the issue? Or did any off the kernel parameters help.



  • @Sebastian-Roth I tried all reboot options, none of them works…

    I understand your concern. Actually I don’t care which version to use, 4.4 or 4.11 are both fine for me. I wonder if something was missed or disabled in the kernel configuration, which caused this reboot issue. Now 3.17.3 is not able to work with fog 1.4.0, so that’s why I wanted to compile my own kernel.

    Any way I will try acpi and combination first.


  • Developer

    @Maorui2k What exactly did you try?? There are several different options you can set with reboot=.... Which one did you try? As well you can look into playing with kernel parameter acpi=.... Possible a combination of both might work.

    Don’t get me wrong. You are more than welcome to build you very own kernel and hopefully make things work. But it’s definitely quicker to try out different kernel parameters first and see if things work that way. As I said, latest kernel in FOG is 4.11.0 so if you are trying to build 4.4.0 (which is working in Ubuntu) from plain vanilla source I highly doubt that reboot is working for you out of the box.

    Please keep us posted on this.



  • @Sebastian-Roth I tried this, but still the same issue… I will compile the kernel as you suggested.


  • Developer

    I just found an interesting discussion on hanging reboots in a CentOS forum: https://www.centos.org/forums/viewtopic.php?t=1164

    Check out the information about kernel parameter reboot=.... There seem to be several different kernel options you can try. You can set kernel parameters as individual host settings in FOG.


  • Developer

    @Maorui2k There is a wiki page on how to build a FOG kernel: https://wiki.fogproject.org/wiki/index.php?title=Build_TomElliott_Kernel

    Using the current kernel config as you find it in the git repository (32 bit or 64 bit) you don’t need to go through all the pain of selecting the correct modules…

    Most current kernel is 4.11.0 by the way! So I am not sure if compiling your own kernel will help. Possibly we need to add some magic ubuntu patch to make rebooting possible on your machines…

  • @Wayne-Workman Could you please tell me who I shall contact?

    The reboot is the only issue I got. I tried all other kernels, the reg/clone worked fine, but at the last step - reboot, it just hung there forever. Ubuntu 16 have no reboot issue which kernel is 4.4.0.

    The CPU is Intel Celeron CPU N2820. I’m not sure what info I shall provide, please just tell me.
