Hello,

using 2.6.30-rc6, I get the following problems when I read from a SSD
disk, connected to the
3.0 Gb SATA controller of the MPC8315E SoC rev 1.0 running Linux 2.6.30-r=

c6.

Below see the output from two dd read runs.

The disk behaves fine on a x86 box.

What I can do to (help) pin-point the problem?

Regards,

Leon.
