    It's nice to see you making a few exceptions to that rule.

    The link Gilly posted doesn't work!

    The requested conversation cannot be found. It might have been deleted.

    I one Googles ...... "Summary of findings rCo 2017 iMac (iMac18,3) with
    Fusion Drive issues"

    I get this result:-

    Summary of findings - 2017 iMac (iMac18,3) with Fusion Drive issues

    I'm running a 2017 iMac (iMac18,3) which originally shipped with a 2TB
    Fusion Drive.

    Based on behaviour over time, my assessment is that the SSD portion of
    the Fusion Drive has failed, while the 2TB spinning HDD remains functional.

    Current setup and observations:

    macOS Ventura is running from an external 1TB SSD and is stable and
    performs well

    Linux Mint 22.3 is installed on the internal 2TB HDD (spinner) and also
    runs reliably

    The same hardware shows instability only when macOS interacts with the
    Fusion Drive configuration

    Kernel panics previously observed (including namespace 2 / SIGBUS-style
    errors) ceased once macOS was moved entirely off the internal Fusion Drive

    This strongly suggests a partial Fusion Drive failure, which macOS/APFS
    handles poorly when one physical store (the SSD tier) becomes
    unavailable or unreliable. Linux, treating the HDD as a simple block
    device, is unaffected.

    Diagnostic/benchmark tools show reasonable performance for the active
    boot device, but they do not expose intermittent Fusion metadata or
    tiering failures.

    Conclusion:

    CPU, RAM, GPU, and logic board appear sound

    Internal HDD is serviceable

    Fusion SSD blade (or its metadata) is the likely root cause

    Running macOS from an external SSD and Linux from the internal HDD is a
    stable and practical workaround

    Posting this in case it helps others with similar 2017 iMac/Fusion Drive symptoms
