We have two different test results here:

    [    2.668190]   Magic number: 1:317:893
    [    2.668302] tty ptyy3: hash matches

and:

    [    1.776755]   Magic number: 1:940:309
    [    1.776782] tty ttyxc: hash matches
    [    1.776846] tty tty38: hash matches

Both list tty devices as the culprit, if we assume that this is not a
totally bogus match in either case then the tty device driver is
fingered.  In both cases the device mentioned is most likely not a real
tty.  One looks to be a master pty, the other may well be a USB tty
device.

The debugging here is a little odd I would have expected to see files
listed in addition to the device being hashed.  I also see that the
userdata is non-zero which implies we completed the resume of something,
possibly in error.  I have added some more trace markers to the resume
side of things to see if we can better tell what is failing if you could
try the kernels at the URL below and report back here.  You will need to
turn on the debugging as you did previously:
