Kernel 5.10.37 doesnt boot

pietinger · Posted: Sat May 15, 2021 9:27 am Post subject: Kernel 5.10.37 doesnt boot

Today I tried 5.10.37 coming from 5.10.36 (with "make oldconfig") on a Gigabyte Z270X-K5. It compiled with no errors or warnings.

Before I had an Update of the Intel Microcode also (I have intel-ucode/06-5e-03). So it is also possible this is the reason.

Anybody else with this problem ?

P.S.: It is a stub kernel which will be loaded from UEFI directly. No errors or screen output; only black screen and BIOS trying to load again.

Fails to boot here, as non UEFI.
µcode updated here, not causing any issue with 5.12.4.

Didn't fallback to previous firmware yet.

Thks 4 ur attention, interest & support.

This will be of neither use nor comfort, but that's why I settled on installing grub as my boot manager, and having a suitable grub.conf to select new, current and old kernels.
The trouble with the EFI stub is that it tells BIOS (or rather EFI) that your linux kernel is a bootloader, but that's really a lie - it's just a kernel that implements the EFI bootloader ABI. It's great until it breaks :-(

Easy to switch kernels with sys-boot/refind using keyboard

It would be nice if buddies with easy kernel switch capabilities could effectivly test 5.10.37 bootability.

Updating portage to get 5.10.37
First I have 218 updates to build. i notice that they are amending ebuilds without revbump. Example: guchar unconditionally requires vala even if -vala flag is set. if a flag dopes nothing, why have it? and why not revbump the ebuild?

When I'm all through, I can report if 5.10.37 boots on ryzen. I still don't think that it proves anything for intel, but it's a data point.

Still encourage OP to install refind instead of stub kernel. For one thing when you build a new kernel it becomes default without any extra commands.

Updated 217 packages (ugh another python change), keyworded gentoo-sources-5.10.27 and built it. Interestingly, the only config change was breaking GCC-NATIVE into two listings, one for Intel and one for AMD (why? gcc can determine amd or intel!).
Will test tomorrow

EDIT"
Wait a minute! You are taling about 5.10.37 but only up to 5.10.32 is in the tree! As of this afternoon.

EDIT2:
Forget it. i was looking at the wrong machine. on the right machine:

Ah? I used gcc-9.3
Reading lots of problems with 11 on the forum.

Thanks for the heads up guys. I'll refrain from updating my intel laptop's kernel then.
On my old AMD desktop (FX-8350) 5.10 was unusable (wayland crashes).

I'm starting to dislike 5.10 -series...

Yup. I suspect its either my GPU, R9 Nano, or the CPU FX-8350.
Gotta suffer with that old CPU until chip makers' supply chain starts working again.

As for intel side of things - I'll wait and see how people manage with later updates to 5.10...

I have just booted Kernel 5.10.38 without any problem.

A diff of "dmesg -t" from 5.10.36 and this one showed me:

1. I have a new microcode; from old "e2" switched now to "ea" (2021-01-25). (This was the microcode update between 5.10.36 and ..37). So, I know the microcde was NOT the problem.
2. I have one new log-entry:
