--- Comment #25 from James tao (tao1hua@...yun.com) ---
I am working on Broadcom ARM chipset base on Android 7.0. I met the same
problem. and the kernel version is 4.1.20.
I set a tf card as "internal share storage". When I try to copy a file(file
size must more than 2.3G) from data partition to sdcard(the filesystem of tf
card is ext4). 
 cp /data/xxx.data /sdcard/ 

the Kernel print log:
[  982.761411] EXT4-fs error (device dm-1): ext4_validate_block_bitmap:380:
comm kworker/u4:2: bg 17: block 557056: invalid block bitmap
[  982.815546] EXT4-fs (dm-1): Remounting filesystem read-only

TF card mount as readonly.
