Surface Pro 4 won't get to registration menu

[sarge_212]

@Tom-Elliott
Correct, the surface pro 4 does not have an onboard nic. Let me compare output but I think the USB nic is plugged in when I ran this. I might be able to boot from the USB stick in the dock and with the 2.0 USB network adapter plugged in, would that be helpful?

[Tom Elliott]

@sarge_212 I think/hope so maybe. I don’t really know though,

[sarge_212]

@Tom-Elliott So I tried that, with the USB network-adapter, and it just added a device in the output of lsusb. Not sure where to go from here.

@sarge_212 You might wanna try this bzImage_epk kernel image. Download it and put it into /var/www/fog/service/ipxe on your FOG server. I compiled this kernel with something called earlyprintk enabled. Possibly we see some more information before we hit the kernel panic. I mean use this kernel and try PXE booting your device with the USB NIC. Just use this kernel binary instead of the normal one. Plus use earlyprintk=efi as kernel parameter for this host - register this host/MAC by hand in the WebGUI, add the kernel parameter to it and run a debug task with it.

[sarge_212]

@Sebastian-Roth So I can manually register the host in the WebGUI with the MAC address? I will try that out.

[sarge_212]

@Sebastian-Roth I’ve done the manual registration and pushed the bzImage_epk to the host with the kernel arguments and it did give a lot of text printing before the kernel panic. Video coming soon…

[sarge_212]

@sarge_212 Here is some video output of the pxe boot and kernel panic. Hope this helps!

@sarge_212 Thanks for the video. I get the impression but it’s impossible to read what’s going on there. Are you able to take a series of pictures? Most cameras can do this. And having the camera in a fixed position would also help I guess. As a start, can you take a clear picture of the full screen when it gets to the end (kernel panic). Possibly we see something there already.

[sarge_212]

@Sebastian-Roth Sorry! Yeah I can do that.

@Sebastian-Roth I would think if you could get the camera in a fixed postiion and then only try to record the bottom half of the screen (sharply) then that may yield better results. I did see that my iPhone 5 has a slow motion mode (120 fps) that would allow more time to try to read the information before it scrolls off.

[sarge_212]

@Sebastian-Roth Yeah I have an iPhone 6 with the Slo Mo, think that might be of help ? The bigger problem is a fixed position. IF only we had a selfie stick in the office!

[Sebastian Roth]

Doesn’t need to be in a self standing position I reckon. Would be a lot better if you can arrange things so that your phone is “standing” on ground (table, books, …). That way the shaking is a lot less. Best if you can cramp it in between two books to make it stand by itself… you will figure it out I am sure.

[sarge_212]

@Sebastian-Roth Genius! Give me a few minutes here…

[sarge_212]

Sorry for the delay all. Here is the latest output from the bzImage_epk argument:

[Sebastian Roth]

@sarge_212 Well done!! Readable and now I am pretty sure what’s wrong. Two important kernel parameters are missing: init=/sbin/init initrd=init.xz (can’t see them when kernel command line is printed at around 0:30 in the video)

I am not sure why but just for testing can you please add those to the kernel options for this host and try again??

[sarge_212]

I also tried with the bzImage_rb as described here:

https://forums.fogproject.org/topic/6525/pxe-boot-hp-x2-210-hybrid-tablet-windows-10-pro/114?page=1

and I am still getting a kernel panic. I noticed that Matthieu finally got it working and I’m wondering what is different, eg (bzImage, ipxe.efi maybe) @Sebastian-Roth if you could let me know I would greatly appreciate it! Thanks!

[Sebastian Roth]

@sarge_212 Your device is totally different than Mattieu’s! From what it seams his tablet has a UEFI firmware bug. I am pretty sure you don’t have that and in your case it’s just the kernel options. See my previous post!

[sarge_212]

@Sebastian-Roth Awesome, I’m trying now!

[sarge_212]

@Sebastian-Roth A couple of questions good sir. When I set the parameters for the image, is it a single disk or multiple disk with partitions, there are 4 or 5 options there. Also, I am using bzImage_rb, should I be using that? It got to the point of NFS mounting and then failed with NFS mount. The NFS service is running, so I’m not sure why it’s failing.

[Sebastian Roth]

@sarge_212 Sorry got to head for a train very soon now. Just a few hints. I’d try “single disk multiple partitions” (non resizable!) first. If that works you can try other image types as well. All those bzImage_* kernels on my google drive are mainly with added debug output and should not run any better on your Surface than Tom Elliott’s standard kernel AFAIK. So try whichever you like but I really hope that the default kernel should work as well. Just the missing kernel options/parameters seam to cause the problem I think. About NFS: Can you upload from other PCs? Maybe it’s a generel NFS problem you see. Search the forum and wiki on how to troubleshoot NFS errors!
