Lenovo Yoga L13 booting to fog
-
@John-L-Clark ok to collect those logs we’ll need to install wireshark on a witness computer (i.e. a second computer on the same subnet) and grab a pcap that way.
Use the capture filter of
port 67 or port 68to only grab the bootp stuff. -
Is this what you need? Thanks
-
@John-L-Clark This doesn’t appear to be a wireshark pcap file, but a text file with pcap data. How did you collect this?
-
@george1421 So now it is booting to the fog menu and I select full host registration and it reboots and goes to
-
@george1421 I used wireshard but saved it as a text file. I have the pcap also. I renamed it and added it.capture.pcapng.txt

@John-L-Clark OK I have it lets switch over to chat for quicker turnaround. Look at the chat bubble at the top of the forum panel

@george1421 Thank you for all your help. Updated Kernal helped with the new network adapter.

Ok we have a solution here after debugging and chatting for quite a bit.
This Yoga L13 has a built in network adapter that is connected to ethernet through a port replicator/dongle. It is not a USB/USBC type adapter its just a port replicator.
Debugging showed us that two nics installed.
Network Controller 8086:02F0 Ethernet Controller 8086:0D4FThe 8086:0D4F ethernet adapters comes back to a Intel I219-V. Looking at the kernel driver database that network adapter was first added to the 5.5.x linux kernel. Both 4.19.101 and 5.1.6 kernels that the FOG Project offers are too old for this hardware.
ref: https://cateee.net/lkddb/web-lkddb/E1000E.htmlTo test/solve this problem I built a one-off linux kernel v5.5.3 using the FOG configuration file from a recently create one off kernel I had for Mac T2 workaround. The 5.5.3 kernel built ok and tested ok in the OPs environment. With the 5.5.3 linux kernel the target computer was able to complete a full registration and the OP said he was going to test imaging later.
So for this issue the answer was to create a one off kernel of version 5.5.3 until the FOG Project releases an official kernel that is at linux version 5.5 or later.

@george1421 Great work!!! Do you know if this driver was defaulting to be enabled or disabled in the kernel config. Just wondering where I would note down that information to not loose it till we get to use 5.5.x or newer…
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

@Sebastian-Roth The driver was enabled. The issue is the hardware ID were not in the driver. It was introduced in the 5.5 kernel. So I took the same config I used for the 5.4.6 one off kernel I used for the Mac T2 chip work around and just recomplied it with 5.5.3. No changes were made to the config file other than opening it with
make nconfigand then saving the config to strip out any deprecated settings. -
Sorry if i’m missing something here but I have this same issue with the same device.
I wish to use UEFI so ipxe.efi?
How do I as a N00b get this to work?
I’ve updated my kernal to 4.19.101, but i don’t see any 5 versions ?
update - i’ve updated fog to 1.5.7, using ipxe.efi but still a little stuck.

@ITCC You will need to use a different kernel that is not officially available. @george1421 will help you with that.
-
@ITCC Here is the link to the one off kernel for FOG. This is version 5.5.3 https://drive.google.com/open?id=1thopskSYJd7ueDQeFg_VT4eeNcrNHvIx
Understand this kernel is not supported by the FOG Project as of now and should be considered a development kernel. The only reason is that it has not been aggressively tested in every environment. It does seem to help with this specific model of computer. -
And if i want to go back to another kernel due to other hardware having issues, i can just download from the in fog menu?
-
@ITCC I would follow the instructions here:
- Download this kernel as bzImage533 (watch your case. Case is important to linux)
- Move this kernel to /var/www/html/fog/service/ipxe directory.
- Manually register this lenovo if it hasn’t been already.
- Go into the manual registration for this host and add
bzImage533into the kernel field. - PXE boot the target computer.
If this kernel works for the yoga you have 2 decisions.
- Continue to set the kernel parameter from each and every computer that needs this kernel
- Go into FOG Settings -> FOG Configuration and set the kernel parameter that will change the default kernel for all computers.
