with both devices plugged in, about 1 in 10 cold boot starts - both
plugged in USB 3 port and both plugged in Type C port
The 2 Type C cables used, are those from the Google Play Store, for the record.
cbmem attached for each.
It looks like in both of the failure logs that the super/high
confusion delayed the usb3 connection notification past the time
SeaBIOS was looking for connection notifications. I suspect you could
get around this by increasing "etc/usb-time-sigatt". (For example, by
adding "$CBFSTOOL $CBFSFILE add-int -i 300 -n etc/usb-time-sigatt" to
the "Other settings" section of the chrome image building script I
previously sent.) This "secondary failure" after patch 47 is one of
the reasons I'm not sure how to really fix the dup drive issue.
