mmc file reads truncated randomly with linux-linaro-arndale

[Riku Voipio]

Using latest image ( arndale-quantal_server_20130221-253.img, kernel
linux-image-3.8.0-1-linaro-arndale=3.8.0-1.1ubuntu1~ci+130221022159 )

It looks like reads from external sd card are sometimes truncated.

This can been seen randomly for example

apt-get install qemu-system
 - dpkg will complain about a missing final newline in a lists file. When you look at the file, it is indeed truncated. After you reboot and look at the file again, it is ok.

sometimes while compiling - this leads to segfaults in compiler or other problems:

After reboot, file is ok again.

I was not able to reproduce this with 3.6 based image linked from the EnterpriseUbuntuServer page:
Linux linaro-server 3.6.0-10612-g9d11689 #11 SMP PREEMPT Mon Dec 3 16:04:32 IST 2012 armv7l armv7l armv7l GNU/Linux

I've updated on monday to the 13.02 release image (arndale-quantal_server_20130224-256.img.gz ), and have not been able to reproduce this since, so this is probably fixed.
