Just updated CentOS 9 Stream on a Lenovo T17 Gen 4 Intel and not it won’t suspend with the following error:

Kernel:

5.14.0-404.el9.x86_64

How do I boot the previous kernel?

Holding Shift down does nothing.

Pressing escape brings up some kind of emergency screen that has no options other than to “Press any key to exit”.

Is CentOS 9 Stream considered stable enough to use as an everyday desktop?

    FYI

    After reverting to 5.14.0-388 yesterday, stability is restored. I can consistently suspend and resume without issues.

    In hindsight, kernel 391 was also giving me issues. My wired network would sporadically fail to come up after suspend. No amount of fiddling would restore. Only rebooting. I have not seen that behavior with 388 either.

    This would suggest an issue with networking / suspend between 388 and 391.

    Q: If I update, am I going to lose kernel 388? How can I persist that one specific kernel indefinitely and still be able to update the rest of the system?

    # grubby –info=ALL | grep ^kernel kernel=”/boot/vmlinuz-5.14.0-404.el9.x86_64″

  • Just FYI

    I updated to 5.14.0-410. The login screen appeared for 2 seconds and then it dropped to console with:

    Failed to start: Crash recovery kernel arming

    Tried to reboot but it hang on the splash screen. The console shows
    “Failed to start …” for all services like ModemManager and so on.

    Rebooted back into 388 and it’s running fine again.

    So it looks like my stability is getting worse for me with each update …

    I’m getting worried about hanging onto 388.

  • The currently booted kernel will never get swapped out when you are updating, so this should not be a concern. Have you reported your issues on JIRA though?

  • Well it just happened with 388 too. Coming out of suspend (power button), the network didn’t come up. Tried gracefully closing terminals and logging out but it hanged up. After about 5 minutes Wayland did log out but then it got really hard stuck (no mouse or keyboard) on some kind of half-baked gdm screen. Had to hold the power button down for a while. Come up ok back into 388 ok.

    Here’s /var/log/messages starting from previous suspend. Trouble starts around first 15:50:05 timestamp.

    Names have been changed to protect the guilty. I’m going to remove this after a day or so so download it now if you’re interested.

    Hopefully it helps someone figure out what’s going on.

    I’m not doing anything exotic. I don’t have lots of crap installed. I’m not watching videos or listening to tunes. Just coding java over NFS in terminators.

    Do you have a link to instructions for posting to Jira? I’ve been writing C and Java since the 1900’s so I might actually be able to get the diagnostics you really want.
