Sorry, I hate to have to go to the forum with a “TW doesn’t boot anymore”, but the sad truth is I am somewhat lost.
I updated TW this morning to 20220410 with the customary “zypper dup”, in addition allowing vendor changes with “–allow-vendor-change”. It gave me kernel 5.17.1-1. In order to complete the update, I updated may grub configuration, and I checked for config file changes with “rpmconfigcheck”.
Admittedly, I had not updated my TW for a few months. The last kernel before had been 5.14.14. Not sure about the TW release date back then - December 2021 or January 2022?
No other changes had been done to my TW system for a very long time, it has been running perfectly. The original installation had been in 2019, and I can say I am very happy with its performance and stability.
After the update today, TW won’t boot into the latest kernel 5.17.1-1.
Booting into both my older kernels present, 5.14.14-1 and 5.13.0-1, works without any problems.
During start-up, the following messages on screen are IDENTICAL for all of my kernels, including the 5.17.1-1:Loading Linux [version] …
Loading initial ramdisk …
bbswitch: No suitable _DSM call found.
nouveau [address (?) hard to read]: volt: Type mismatch between the voltage table type and the GPIO table. Fallback to GPIO mode.
I have been getting these messages for quite some time, no problems until now.
However, with kernel 5.17.1-1 today, TW doesn’t arrive at the Plasma screen anymore. After the last message from nouveau, a static underscore character appears for some seconds. Thereafter, the screen goes all black and remains in that state. I let it sit for a couple of minutes. No reaction to CTRL-ALT-F3 or CTRL-ALT-F7. All I can do is turn the laptop power switch off.
My laptop is an old HP EliteBook 8570w. Graphics card is NVIDIA GK107GLM (Quadro K1000M), running on nouveau. Graphics platform is X11. Plasma version now is 5.24.4, KDE Frameworks 5.92.0, Qt version 5.15.2. I am not sure exactly about the latest kernel version: grub and boot message tell 5.17.1-1-default, while YaST2 Software says 5.17.1-1.2 is installed. The TW root disk is btrfs, other disks are ext4 and NTFS; they all get mounted properly.
Sorry again to be lost and without a clue. Please, can somebody help? Let me know what other information I should provide.
What I am thinking about:
Should I regenerate the 5.17.1-1 initial ramdisk, even though there were no particular errors seen when “zypper dup” did this during the update? How to do this without affecting the older ones?
I did regenerate the grub config file, several times even.
