Comment(by wad):
At this point, I've duplicated this success (12K cycles) on six laptops.
There have been no re-occurences of this issue, with one exception:
SHC23800085, an unmodified SKU293 B1 laptop, definitely testing using
Q7B07ja, has thrown a Data Abort on reboot twice now, with a frequency
roughly that seen before (1 per 2K reboots ?).
ftrace, .registers, and keyboard driver info from one of the Data Aborts
is attached. The screen simply said
Data Abort
ok
The keyboard was inoperative, as before. The ftrace is identical, but
the registers and keyboard queue state aren't.
Now that it has been duplicated on this hardware w. q7b07, I will add the
decoupling present on C1 and retest.
