Hi guys.

I've some USB 500GB 2.5" external HDD full of MKV video.
Till one month ago I had no problem: I connect them to frontal USB and they works fine. Kernel 3.2.x

For last month I've not used any external USB HDD.
Some days ago I've upgraded my CT9100 to Kernel 3.3.x and yesterday evening I've done another upgrade session, so my CT9100 is freshly updated.
This afternoon I connect an USB disk and E2 crash....

1) I connect USB disk and, after 10-15 sec. , screen show spinner and E2 is crashed (no response from remote control)

Connecting with SSH to CT9100 I see:

2) disk looks to be mounted correctly
root@et9x00:~# mount
rootfs on / type rootfs (rw)
ubi0:rootfs on / type ubifs (rw,relatime)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /media type tmpfs (rw,relatime,size=64k)
tmpfs on /dev type tmpfs (rw,relatime,size=64k,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
/dev/sda1 on /media/usb type ext4 (rw,relatime,barrier=1)
/dev/sdb1 on /media/hdd type ext4 (rw,relatime,barrier=1,data=ordered)
usbfs on /proc/bus/usb type usbfs (rw,relatime)
tmpfs on /var/volatile type tmpfs (rw,relatime)
/dev/sdc1 on /media/sdc1 type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)


3) dmesg looks fine, no problem

4) there is a process (sleep state) involving ntfs
500 root 3156 S mount.ntfs-3g /dev/sdc1 /media/sdc1

5) If I try
root@et9x00:~# ls /media/sdc1
nothing happen: 'ls' command is freezed as it cannot access to disk.


I must remove USB disk connector and poweroff-on my STB


I've tried 3 different HDD model without any success, all with NTFS format.
In my Kubuntu system and in my Win7 system they work great without problem.


Something strange happen with upgrade to kernel 3.3.x (from 3.2.x)....

NTFS-3g is broken on 3.3.

opkg remove ntfs-3g
opkg install kernel-module-ntfs

And reboot. NTFS will be read-only then, though.

[ambrosa]

root@et9x00:~# opkg remove ntfs-3g
No packages removed.
Collected errors:
* print_dependents_warning: Package ntfs-3g is depended upon by packages:
* print_dependents_warning: task-machine-base

Can I also remove "task-machine-base" or I need to force remove only ntfs-3g ?

[MiLo]

Force remove ntfs-3g (you kinda need task-machine-base)

[ambrosa]

Done:

opkg remove --force-depends ntfs-3g
opkg install kernel-module-ntfs

and reboot

but it doesn't work.

When I insert a NTFS disk, dmesg shows problem and disk is not mounted:

'lsmod' doesn't list ntfs module loaded but module is present in lib/modules tree:
root@et9x00:/etc/modutils# ls -la /lib/modules/3.3.0/kernel/fs/ntfs/
drwxr-xr-x 2 root root 224 May 5 16:45 .
drwxr-xr-x 3 root root 224 May 5 16:45 ..
-rw-r--r-- 1 root root 178176 May 2 02:07 ntfs.ko

So I've manual loaded ntfs module with 'modprobe ntfs' and now lsmod show it
root@et9x00:/etc/modutils# lsmod
Module Size Used by
ntfs 115324 0
...


I've retried and now HDD works. In read-only mode but it's ok for my needs.

So I've created an entry in /etc/modutils
echo "ntfs" > /etc/modutils/ntfs
update-modules

And now all is fine even after reboot (ntfs module is loaded).

Do you need some changes in "kernel-module-ntfs" and add above ?
