1.In this bug,after back to homescreen from browser app through home button,click browser app and open it,but find phone been reset,and loop at the animation of startup constantly.After interrupet of power supply,we restart this phone,we find it could startup normally,but it has no response with our operation at the screen.
2.Through the analysis of /data,we find it would be fine while we replace with a well /data.And other data file is OK.But /data is too full to have any operation.

Dear Vance & Rachelle,

Through the analysis of /data,the total size of minidump files is 130MB.So I think when click browser app,minidump files are too big to make b2g reset.

How do you fill the /data partition? In normal operation, gecko monitors the available space and stops writing to disk when we fall under 5MB of free space, and only resume writes once we have more than 10MB available. Can you confirm that you have fanotify support enabled in your kernel?

See kernel/arch/arm/configs/sp7715ga-native_defconfig

CONFIG_FANOTIFY=y

We have enabled it.

Dear Fabrice,

   OK,We have enabled it.Because sprd_QA reproduce this problem with debug version,so probably too much slog to make /data full.I would reproduce this problem with user version,after reproduce I would add more information of it.
   Thanks.
