Error with EXT4

[pedrodurek]

Hi, i am using the buildroot tool to build a custom embedded system from Debian, but i am having some problems with the EXT4 in two partitions:

EXT4-fs (mmcblk0p2): error count: 1
EXT4-fs (mmcblk0p2): initial error at 6: htree_dirblock_to_tree:920: inode 121: block 4383
EXT4-fs (mmcblk0p2): last error at 6: htree_dirblock_to_tree:920: inode 121: block 4383
EXT4-fs (mmcblk0p3): error count: 2
EXT4-fs (mmcblk0p3): initial error at 1414772751: ext4_put_super:774
EXT4-fs (mmcblk0p3): last error at 1414772751: ext4_put_super:774

And this erros is occurring in +- 20m after Kernel be started, and in that moment i can't check or start any service of the systemd, for example, when i write the command "systemctl status" the return of the terminal is "Failed to get D-Bus connection: No connection to service manager.". If someone can help me, i will be grateful.

My fstab file:
# <file system> <mount pt> <type> <options> <dump> <pass>
/dev/root / ext4 rw,relatime,data=ordered 0 1
/dev/mmcblk0p1 /boot vfat ro,noauto 0 0
/dev/mmcblk0p3 /var ext4 rw,relatime,data=ordered 0 2

My boot file:
dwc_otg.fiq_fix_enable=1 sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait quiet console=tty1 selinux=0 panic=5

this really is not raspbian then , it should be elsewhere
unless you are using raspbian to buildroot something else
if that is the case then you need to make sure you have got full power available to the RPi and you are not browning out and causing write errors...
