Boot fail: hangs at LibreELEC beta splash screen [LE 7.95.2]

1st Official Post

    Kodi splash screen never appears
    gdb terminates & restarts every few seconds in endless loop
    issue was seen on Pi v3 and Play v1

    some possibly relevant dmesg excerpts...

    note: last 3 lines in code box above repeat continuously

    Do a clean install?

    oh I see, its an in-Kodi issue then, not a shell script error

    kodi.log says

    Code

                                            Query: SELECT idVersion FROM version

    so here is the problem:
    /storage/.kodi/userdata/Database/Addons27.db was zero length

    deleted it via SCP and Kodi recreated it immediately by copying Addons26.db to Addons27.db like it should

    then Kodi finished loading right away
    so... database migration error then. whys it only fail on some systems and not others though?

    in any case you can trap this, right?

    If Addons27.db = 0 bytes at launch -and- Addons26.db = nonzero, delete/recreate Addons27.db

    Like it should? I'm guessing Addons27.db will have changes compared to its previous version.

    yeah, I meant to say "migrate" like it should rather than copy, cause YES, it's not necessarily gonna be an exact copy -- I got that, okay?

    just delete Addons27.db so Kodi can upgrade via the normal upgrade procedure.

    That is exactly what happened. I do believe I said that clearly enough:

    "deleted it via SCP and Kodi recreated it"

    If Kodi recreated it, and that can only occur through auto-migration, it should be obvious the upgrade took place as designed. My question is why did it fail in the first place. If you don't know, consider it a rhetorical question - just something for devs to be aware of. I really did not need to post my solution at all, just trying to help the other guys with the same problem.
