Subject: oops on cubix-i

Dear Kernel Hackers,

I am getting kernel oopses on my cubox-i (i2ultra) running
Linux 3.15-rc4, when using the box as a samba server with 
a local attached 8 GB usb stick. (it also happen with a smaller
video on the micro-sd card)
The oops happens while playing a movie (4 GB file) on a samba client 
(macos x maverick macbook) via vlc (after 5-15 minutes). 
Both systems are connected to a gigabit ethernet switch.

The oops happens with ntfs-3g, ntfs, vfat and ext4 filesystem.

Oops, dmesg and kernel config are attached.

This also happens with this patch applied:
http://www.home.arm.linux.org.uk/~rmk/cubox/hummingboard-cubox-i-v3.15-rc1-20140424.diff

And it also happens with firmware added to imx-sdma driver.

smbd --version                                              
Version 3.6.23
uname -a                                                      
Linux cubox-i 3.15.0-rc4 #1 SMP Fri May 9 12:58:45 CEST 2014 armv7l
GNU/Linux

The system does not always crash completely, but sometimes.

Thanks for any ideas.

best regards
 Waldemar
