    Dear Maintainer,

    In the kernel logs I found the following log: "thermal
    thermal_zone8:
    failed to read out thermal zone (-61)", the only problem I find is
    that
    power-profiles-daemon doesn't set the performance mode because it
    says
    that the temperature is too high even if it is not true (bug I
    already
    reported).

    Can you verify this against the most current kernel in the 6.1.y
    stable series? (6.1.128-1). Does the problem shows up as well with a current kernel from the upper suites ideally 6.12.15-1 to test or (6.13.3-1~exp1 from experimental)? Is the problem exposed there as
    well?

    In the case of yes, can you provide the kernel log showing the
    problem
    and could you report it upstream to the linux-pm developers?

    Regards,
    Salvatore



    Hi,
    the problem goes away with kernel 6.13.4-1~exp1 and the latest firmware-iwlwifi (sid).
    The power-profiles-daemon problem remains though.

    Thanks for reporting back. If you have enough spare cycles you might
    try to verify as well 6.13 mainline, if its fixed there then do a
    bisect of the upstream changes between 6.1 and 6.13.

    I would suggest to first narrow down more the upstream versions by
    fetching the kernel revisions from the snapshots service. Once you
    have a close enought range of upstream versions then do the bisection.

    if you are able to determine the fix and it's missing in 6.1.y we
    might try to prod upstream to have a backport to 6.1.y as well, but we
    first need to get an idea about the fix.

    Regards,
    Salvatore

    Might be this one: a8a261774466 ("thermal: core: Call
    monitor_thermal_zone() if zone temperature is invalid") in which case
    the unstable kernel should as well do not expose anymore the log
    error.
