Thanks for the report.
As bisection, can I summarize as below table?
d56c261e52 firmware IO_PAGE_FAULT
(CQM support)
--------------- ----------- -----------------
o 0.29.29.7 yes
o 0.29.29.5 no
x 0.29.29.7 no
x 0.29.29.5 no
If this table is correct, we will check the beacon filter feature in firmware.
