Hi,

While is testting LTSI-v4.1.13-rc1, we have found the following the 
failure of mmcif.
1. mount mmc block
2. write data to mmc block
3. suspend/resume
4. write data to mmc block one again => happen kernel panic
(Probability in this test procedure is 100%)

We have used git bisect to find cause of failure in LTS-v4.1.13 to 
LTSI-v4.1.13-rc1
and have found commit which cause failure.
(On LTS-v4.1.13 has not this failure)
  drivers: sh: Disable PM runtime for multi-platform ARM with genpd
  commit :cbc41d0a761bffb3166a413a3c77100a737c0cd7

Please confirm for this failure with error log on Lager(Rcar-H2).

Best regard,
Nguyen Viet Dung
