4.2.0.93-rc8 (+local patches of SeqV3 applied)

hi,

today I just compiled rc8 with the seq3 patches enabled,

and starting the device 3 times, where one time the display is visible,
in the other two cases like in this dmesg, the screen is black (with backlights
seen at the borders like everytime).

I have no idea what, but I think its an timing issue, because of the statistics
that of rebooting the device often, that sometimes I got a screen and most of
the time it does not get attached or whatever.

The bit banging message was also one of my possible issue canidates, but I
cannot prove it yet.

the next attachment is again with full visible screen (KMS working as expected
and running an older weston version)


thank you so far for the help by the way
