    I got a permanent black screen this morning. And after I rebooted
    via ssh (as I couldn't have any other access to the machine), the
    logs show issues with nouveau (see attached file).
    [...]

    The logs show a lot of WARNINGs, so I've filtered and categorised those:

    The driver attempted to decrement a reference count that was already 0.
    This quite likely indicates a use-after-free, which is very bad news.

    the laptop screen). This is bad, but this has always been like that:

    Does this mean that you have a reliable way to reproduce this problem, including the WARNINGs? If so that would help a lot with testing any
    possible fix.

    I've looked at the logs. Each time this occurred, this is when
    I disconnected the dock (on purpose) or when I reconnected it
    (in the later case, the system was resuming from sleep).

    But when I disconnect the dock, this does not always occur.

    I could also noticed that on November 6, I got a crash when the
    system resumed with the dock connected, but this did not involve
    nouveau:
