Thinking about this a bit more, it would also be interesting to know what modules are loaded by what kernel modules were loaded by the live boot OS. You would use lsmod and probably direct the output into a file.

@Matthieu-Jacquart Hope we’re not asking too many things here from you. But would it be possible to take a short video of the whole bootup process. Sometimes there are small hints that we only see if we have it right in front of our eyes…

@Matthieu-Jacquart My intent was to not send you in 20 directions all at once. But since a live boot works, once you get the debugging information for the devs, it would be interesting to know what the output of lsblk and lspci -m are.

I’ll reiterate this. This is easy to get and important to know.

At least now I know it’s not bad downloaded files and what not.

ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz} on fog server give me

root@FOG:~$ ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}

@Sebastian-Roth Yes other client works perfectly, I deploy image yesterday and no problem. I didn’t see more output when I tried to boot on tablet

@george1421 Ok I’ll give you the result of command on Monday, for now I’m at home

[Sebastian Roth]

@Matthieu-Jacquart There is no log file. You will see more output on the screen when your tablet boots up - if so. But maybe you won’t see any more information. Can you boot other clients properly? Just asking to make sure your kernel/inits are fine.

[Tom Elliott]

How about we get:

ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}

First.

I’m still guessing these files didn’t download properly last time.

@Sebastian-Roth
I increase FOG_KERNEL_LOGLEVEL to 7 and activate FOG_KERNEL_DEBUG, which log can I look at after ?

I can boot on ubuntu live USB, it works perfectly

[Tom Elliott]

@Sebastian-Roth I’m still under the impression it’s related to the files not having the right content, but I could be wrong. It happens a TON!

[Sebastian Roth]

@Tom-Elliott Hmm, but I guess Matthieu’s setup is working for other devices, right?

@Matthieu-Jacquart As you are using FOG trunk (signature), can you please try to increase kernel loglevel and enable debug. You can find those settings in FOG configuration in the web GUI. Maybe we see some more info then.
As well I really like George’s idea to boot any kind of live Linux from an USB thumb drive to see if you can get Linux up at all.

[Matthieu Jacquart]

@Tom-Elliott I’ve just tried intel and realtek.efi,

DHCP failed...

First time (in my original post) I tried ipxe, snp and snponly.efi, and always black screen after bzimage and init.xz…

[Tom Elliott]

@Sebastian-Roth The only other time I have seen the black, is the files are html files, not actually downloaded files (bzImage/inits).

[Sebastian Roth]

@Tom-Elliott Maybe I am wrong but I think George is right about Matthieu’s request. Sounds like iPXE is working fine (using ipxe.efi/snp.efi) as it comes up with the menu.

Any option I choose, screen stay black after loading file bzimage and initzx …

Black screen after loading the kernel. It could still be related on how iPXE is loading the kernel on those devices but we don’t know yet I reckon.

[Tom Elliott]

@george1421 As it’s not getting that far in, I think it’s driver related on the iPXE side.

Maybe, try the intel/realtek.efi files?

[george1421]

You are right, it seems to be a common thread with the tablets this week. There is something in the linux boot kernels that does not like these tablets. I think we really need to find out the geometry/layout of these devices.

If you can, please try to usb boot a linux live image on these tablets. Pick the latest release of ubuntu desktop. If you can get that running then we can run a few commands like lsblk and lspci to find out the exact structure of the storage and devices installed in the tablet.
