Jetson TK1 from First Choice Keeps Failing

Hello all,

We are having issues with our Jetson TK1 which received from First choice.

It is running the latest Jetpack 2.0.

It starts up fine, and I can ssh into it to load custom made programs. However, after a while the file system auto mounts itself as read-only.

If I recall correctly, this is automatically done by ubuntu to protect the file system if it detects some error which can make the system unstable.

So this lead me down a faulty hard disk path.

running a few commands I get the following
Code:
dmesg | grep "EXT4-fs error"
Quote:
[ 42.960625] EXT4-fs error (device mmcblk0p1): ext4_mb_generate_buddy:755: group 5, 3697 clusters in bitmap, 3696 in gd
[ 87.527366] EXT4-fs error (device mmcblk0p1): __ext4_journal_start_sb:62: Detected aborted journal

and

Code:
sudo fsck /dev/mmcblk0p1 -y -c -f -b -l
Quote:
/dev/mmcblk0p1: ***** FILE SYSTEM WAS MODIFIED *****
/dev/mmcblk0p1: ***** REBOOT LINUX *****

Error writing block 32768 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Error writing block 163840 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Error writing block 229376 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Error writing block 294912 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Error writing block 819200 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Error writing block 884736 (Attempt to write block to filesystem resulted in short write). Ignore error? yes

Not sure where to go from here. It looks like the disk has a hardware failure. This report goes on for miles.

Any recommendation on a fix, or anyone know whom or how I can contact NVIDIA when related to a FIRST item?

Thanks,
Kevin
