Boot failure after security updates

[krsengr]

Problem:
Security updates after upgrade, killed system.

Specifically, system won't boot using 5.3.18-150300.59.43 unless I use the "safe-mode" selection. Works OK 5.3.18-59.40-default kernel.

Symptom:
Screen goes dark after ramdisk loads, both monitor loose signal and no activity on harddrive after a few seconds.

Troubleshooting / Remediation Steps
1) Using [AMD/ATI] RS780L [Radeon 3000] card, so suspected Bug 1195142

Tried:
# mkdir /lib/modules/5.3.18-*.43-default/updates
# cp /lib/modules/5.3.18-*.40-default/kernel/drivers/gpu/drm/radeon/radeon.ko* /lib/modules/5.3.18-*.43-default/updates/
# depmod 5.3.18-150300.59.43-default
# mkinitrd

This didn't seem to change anything.

2) Removed quiet boot options and add debug, I see lots of boot-up activity and screen then goes black after about a minute. No red flags or errors that I could see, it just goes dark at 66 seconds. There is some radeon messages ~57 seconds, but no errors that I could see. Used cell phone to record scrolling and captured last frame before darkness.

Request
I hate to run with an unpacked system, but I'm not sure how to get around this.

I welcome any suggestions on how to isolate or remediate the problem. Thanks in advance.

Don't you still have the 59.40 kernel installed to boot from?

I only tried those bug instructions for one installation, though not exactly. Instead of to updates I copied over the original. After that one I've been installing the kernel from here instead of messing with the bad one. On my main installation I'm still running on 59.37.

Yes, I can boot to the old kernel, which is what I'm doing now. I just wanted to know the root cause so I can see when it's resolved and keep up with patches.

I'm having the same problem. Now booting from 5.3.18-59-37. Are you saying that 5.3.18-150300.59.43 is from a bad repository? How to recover?

This is the only weirdo I found in Yast: http://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Leap_$releasever/

I just now replaced it with: http://ftp.gwdg.de/pub/linux/misc/pa...SUSE_Leap_15.3

Am I supposed to be using https://download.opensuse.org/reposi.../pool/x86_64/? All the others use the same base: https://download.opensuse.org/

It's an option. It contains patches that are not in the 59.43 kernel, including one that solves the black screen problem with radeon GPUs.

There's "me too" here. Following for resolution.

Although the work-around didn't fix my problem, the Kernel update to 5.3.18-150300.59.46 did. Problem resolved.

The current kernal that actually works likes like something from "Farscape." Here's my Kinfo:

Operating System: openSUSE Leap 15.3
KDE Plasma Version: 5.18.6
KDE Frameworks Version: 5.76.0
Qt Version: 5.12.7
Kernel Version: 5.3.18-150300.257.g6971cec-default
OS Type: 64-bit
Processors: 6 × AMD FX(tm)-6100 Six-Core Processor
Memory: 11.4 GiB of RAM

I included the OSS debug repositories on my last update.

The actual problem should be resolved with the new kernel from Leap 15.3 by updating.
