[SOLVED] Current I have a problem

Current will install on a Qemu UEFI virtual machine but will not boot tiancore just hangs

Current will install on a separate UEFI partition but will not boot just keeps falling back to the installer.

Working on it
any comments welcome
I have slackware 64 running on NVMe - SDD - spinning rust
I don't think its me
By the way it works fine on legacy both virtual and real
John
just installed on a second partition same problem
I get the TianoCore splash screen
then ELILO v3.16 for EFI/x86_64
then Loading kernel vmlinuz... done
then back to the splash screen

Hello !

I don't think it's you.
I've upgraded my "virtual Slackware" at the same time that I tried to make it boot through EFI with ELILO, and not "Legacy" with LILO. It hung (besides many other infuriating problems with VirtualBox's implementation of EFI but that's another story). So I resorted to go back to legacy and it worked. So far, half so good.
Then I thought that maybe it would work on real hardware since I had many machines boot through EFI for years without a problem.
And then it hung.
I booted a rescue system and changed my elilo.conf file so that it was as verbose as possible.

It hangs while uncompressing the kernel, apparently (see attachment)

I used the latest elilo-x86_64.efi and vmlinuz (found in /boot, using kernel-huge) and the config file is as simple as can be, and worked very well with every single previous version of the kernel images (as packaged, or compiled by myself).

What's so special about this 4.14.0 kernel image ?

sorry you are also having problem. nice to know I'm not alone

anyone care to take a look at the config I have been using since 4.14 was released which works fine for me and the current kernel config ?

Has anyone successfully built a virtual machine of current using UEFI?

the diff is attached

asrock 77 extreme 4 motherboard
i5 intel processor
Linux NVMe 4.14.0 #1 SMP Sun Nov 12 17:30:00 EST 2017 x86_64 Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz GenuineIntel GNU/Linux
the problem is repeatable on pci nvme, sata sdd and spinning hard drive

new update/kernel for current dated Sun Nov 19 03:36:30 UTC 2017 does not help
same loop as before on qemu virtual machine on boot after successful install
I get the TianoCore splash screen
then ELILO v3.16 for EFI/x86_64
then Loading kernel vmlinuz... done
then back to the splash screen
over and over
I can escape to the grub boot manager screen and start the efi shell
with the efi shell i can

fs0:\EFI\Slackware\vmlinuz

starts to boot and I get
Kernel panic - not syncing: VFS: Unable to mount rootfs on unknown-block (0,0)

also from the grub boot manager I can select Slackware
which takes me back into the boot loop at
ELILO v3.16 for EFI/x86_64
Loading kernel vmlinuz... done
and continues to loop back to the splash screen

Today I think I will try to compile and install the current config-huge on a working 64-14.2
maybe that will give me a hint
john

the problem is in the kernel config

I used the config-huge from current to compile the kernel
copied it along with System.map to a working 64-14.2 system and added an entry for the new kernel in elilo.conf to use it as default [REBOOT]

it starts as always with
ELILO v3.16 for EFI/x86_64
.....
Loading kernel bzImage-4.14.0 ... done

and hangs no panic just hangs
going to reinstall my config and wait for new update
John

Looks like we need a modified /boot/efi/EFI/Slackware/elilo-x86_64.efi the huge kernel is too huge >8M There is a patched referenced in another thread

Found the fix for huge kernel too huge to boot

Using the patched elilo from http://vs3.z01.eu/files/elilo-x86_64.efi
The patch alone is available from https://sourceforge.net/p/elilo/patches/19/
I looked at the elilo slackbuild but did not try to do the patch myself (Too complex for me)
So I added the patched elilo-x86_64.efi to my install dvd
built the VM and installed as usual
but before I rebooted I copied the patched elilo-x86_64.efi from install dvd to
/mnt/boot/efi/EFI/Slackware/elilo.efi
rebooted
worked as advertised (Bob's your uncle)

Thanks
John

Yes!

Thank you.

I don't knoow if this thread was a help to anyone other KewlCat and myself, but it helped me work my way thru the problem
So I feel a responsibility to close it out properly
Thanks to Didier Spaier for posting the elilo patch in a another thread
Thanks to Zerouno for posting a reference to a revised elilo.efi in a different thread
Those posts allowed me to test and resolve the issue

And of course many Thanks to Pat for doing the hard part and issuing an update to current which fixes everything that was an issue for me.

The current update issued Tue Nov 21 05:05:41 UTC 2017
installs and boots on a Qemu 64 VM in both UEFI and Legacy modes.
Amen.
Lots of fun in the last few days.
