Hi all,
I use a nxp isp1760 connected to a freescale mpc8270 (custom board).
I'm using the driver from the kernel tree. the controller is well
initialized and my devices are created by udev.
The running kernel is a 2.6.26.8.
I have problems when I try to access to my device /dev/sda1 either
with dd, fdisk or mount.
#fdisk /dev/sda

I think i have the turnarround error described by NXP in their FAQ.
But reading the messages of the mailing list, I think i am not the
only only one in this case and the problem comes often from the mass
storage devices.
It might appends that during a data transfer, the devices stops
sending an ack and the host received only part of the data which
might lead to problems.
Here is the complete trace :
