UEFI SecureBoot: integrity: Problem loading X.509 certificate -74

Post by durchd8.de » 2020/12/17 14:51:49

Holla,

I am not entirely sure if it is a Hardware problem, a kernel problem or a security issue. Hence posting here:

OS: CentOS Linux release 8.3.2011
kernel: 4.18.0-240.1.1.el8_3.x86_64
installation: fresh minimal installation from USB via standard ISO (downloaded several times fromvarious centOS mirrors)

Hardware:
- Supermicro MB1 M11SDV-4CT-LN4F (AMD EPYC 3101)
- 8 GB RAM
- Avago Megaraid MR9341-4i with 4 WD HDD
- NvME: Samsung SSD 970 EVO Plus 1TB

Problem:
Whatever I do upon a new installation I receive the error:

integrity: Problem loading X.509 certificate -74
in dmesg and log.

Overall the system "feels" fine on anything else were it not for that error message. Also this message pops up upon secureboot enabled or disabled. Supermicro support wasnt able to reproduce the error with the hardware, CMOS flush didnt help either, but the hardware is ok.

Reinstalled the system a myriad of times and I plain have no clue whats going on... What did I do wrong or where does the error come from? Attached the last log entries:

Adding to it, I used a slightly older image via USB: CentOS-8.2.2004-x86_64-minimal.iso

Same X509 error even on ISO startup (like all others).

Hi durchd8.de,

Did you solve this problem?
Seems I encountered this same issue when booting rhel 8.3 on Lenovo x3850 X6 server.

There is a Fedora bug entry for the message that is issued that says it's a problem in the RH patches they add to the kernel. I suspect they've helpfully backported the same bug to the RHEL kernels.

Since RH have basically abandoned CentOS Linux 8, I would suggest that you test using CentOS Stream and if that has the same problem then raise a bug on bugzilla.redhat.com under RHEL with the version set to CentOS Stream.
CentOS 6 died in November 2020 - migrate to a new version!

CentOS 5 is dead, do not use it.

TrevorH,

Thanks for the information!

I'd like to have a try when i get a spare machine.
For now, i can only go back to rhel 8.2 for a urgent project engagement.
