--- Comment #15 from Chris Wilson <chris at chris-wilson.co.uk> ---
Still not 100% sure about where the error creeps in, but for now

commit d78200e53e6e5b889a71f79c103aa4e1ba148c95

    sna: Always refresh the blob property before reading

    Ensure that the property value for the EDID is current before
    retreiving the blob.

commit 0196fa2da8140853e9542bf41b63cbd345e857be
Author: Chris Wilson <chris at chris-wilson.co.uk>

    sna: Handle getblob failures gracefully

    As the EDID property blob may be lost at time after we perform the
    detection probe (as the kernel may recreate the EDID blob at any time with
    a new id), presume that if there is no matching property that we can
    simply keep using the last known EDID.
