[Arm-netbook] RAM, uboot

[Mike Thompson]

David,

Thanks to your efforts with the kernel I have a Debian Wheezy armhf
system running on the Mele A1000.  Unfortunately, as I've started to
use this system to run builds of some large Debian packages I'm seeing
infrequent SATA errors that are corrupting the ext4 file system and
causing my builds to fail.

Attached below are the types of errors being reported to the system
console.  These were made over a 12 hours period building a large
Debian package -- something that is pretty disk intensive.

Unfortunately, I don't even know where to begin looking to figure out
the source of these errors.

Are you or anyone else seeing similar errors on SATA mounted hard
drives using the 3.0.31 kernel?

Mike Thompson
