Me too! (Using driver from 2.6.28 backported to 2.6.26).
I am using ISP1760 on a 530 MHz BF 527 board. SCLK is 133 MHz.

Same for me....

May I ask you which bus timing you are using?
I found I have to use a very SLOW timing, else the readout of qh information
is buggy for me.
There are some registers which have a timing period of 195 ns. I have found no
special treatment in the driver to handle this timing requirement. And I have
found no statement from NXP weather this requirement also exists between the
two halves of a 2x16 bit access.....
Can you check with maximum slow bus timing?

Wolfgang
