Dear All,
My customer found a EXT4-fs error case in TF card after several days. Attached is error log. They suspected this is MMC driver bug. They found there is mmc multi block read/write bug revise on Ti git, they are trying to test this case based on Linux 4.1 Do you have any suggestion on this case? Thanks a lot.
Error Log:
EXT4-fs error (device mmcblk0p2): ext4_mb_generate_buddy:739: group 17, 33 clusters in bitmap, 0 in gd
JBD2: Spotted dirty metadata buffer (dev = mmcblk0p2, blocknr = 0). There's a risk of filesystem corruption in case of system crash.
