    Default Booting today stalls system and I con only boot from previous kernel using advanced options

    Have had a bad experience with this system today. Booting was slow and eventually stalled. I re-booted to windoze just in case I had left the system in a bad state. Windoze found errors and had to check the drive. It started OK in the end and appeared to have been stopped mid windoze update. (I had been getting machine ready for office location which uses windoze.) After a couple or updates and restarts of windoze I tried to go back to Leap 15.3 but the system stalled again. I could only get the machine up in Leap 15.3 using the advanced boot option from grub and accepting the previous kernel.
    This ran without a problem and updates were waiting so did a sudo zypper up which included a kernel update. I rebooted to the new kernel but the boot stalled so I have had to go back to the version which works.

    While I go and find a live distro to help diagnose problem does anybody else have this experience. I am running Kernel Version 5.3.18-150300.59.87-default to get this working for now. smartctl --all /dev/sda and /dev/sdb give no errors.

    I will have to read up how to check the /dev/nvme0n1p1 etc. so if anybody can advise please let me know

    Where should I start with diagnosis? I suspect my hardware as it is unusual to have two consecutive kernels going wrong.

    Budge.

    If anybody has time here is my boot log.

    https://paste.opensuse.org/24537981

    For reasons I don't understand I cannot get any previous boot logs using
    Code:
    sudo journalctl --list-boots
    only this last one. At least it did work!

    Perhaps a persistent journal is not enabled?

    See section 11.1 here: https://doc.opensuse.org/documentati...ournalctl.html

    OK, I now have the persistent journal enabled
    Code:
    # 
    # See journald.conf(5) for details. 
    
    [Journal] 
    Storage=persistent 
    #Compress=yes 
    #Seal=yes
    
    I have tried to boot into the upgraded system but this is still stalling. However when stalled the keyboard Caps Lock and Scroll Lock flash on and off.
    The only way I can get out of this situation is to use the off switch on the box.

    I can however re-boot to the kernel two updates ago.
    I am not sure if this is a bug or my very old but till now faithful PS/2 Northgate Omni Key/102.
    In my system settings I can only select the Northgate 101 which is what I have been using to date.
    Not sure if this is the problem so will grab a spare modern keyboard and check.
    What fun!

    I have tried using another keyboard which also has a PS/2 plug and I still get a problem with the latest two updates, again with Caps Lock and Scroll Lock flashing. I have also tried these keyboards with PS/2 to USB adaptor and get the same result.
    Since the older kernel is still working fine I am going to attempt to report a bug but not tonight!
    Meanwhile if anybody else knows anything on this please post here so I know I am not alone!!!

    My one remaining 15.3 machine I updated earlier today to 5.3.18-150300.59.93-default with no issues.

    The Caps Lock and Scroll Lock flashing is signalling a kernel panic. The Linux kernel has experienced an unrecoverable error and cannot continue.

    Don't offhand know where your problem lies.

    I am very jealous. Had I known Northgate would drop off the planet when it did I would have bought several prior thereto. Those I acquired via employers all disappeared by the time I needed another, so I was stuck with one, and it quit more than a decade ago. I'm stuck using these that have gotton well worn.

    I have had trouble similar to the problem you are having within the past month, emergency shell, cannot find root filesystem on NVME. Trouble is, I can't remember which PC or OS, or well enough when to figure it out, even though I only have 3 PCs with NVME in them. Now that I've seen this thread, maybe something useful to you will come to mind sometime soon. Maybe Mageia 9 (devel) on (Kaby Lake) host ab250....

    Hi mrmazda,
    And I thought I was the only one still with Northgates. My main machine uses an Ultra but am using the 102 on this problem machine.

    The problem machine has two processors and a 2GB NVMe drive. This is my basic hardware:-

    Thanks to your advice I am using the updated inxi!

    Thanks for the info on the flashing lights. New to me but a good indication of what might be going wrong.
    My question, not yet researched, is how may I test the NVMe in the same way that a hard drive is checked? I think I should start there as the update has not caused problems on other machines so hardware is prime suspect. OTOH this machine is still running fine on earlier kernel version.
    I look forward to your advice please when you have time!
    Many thanks,
    Regards,
    Alastair.

    This means kernel panic. Boot with "plymouth.enable=0" and without "quiet" on kernel command line, this may give more output on console.
