ok, i will test out this patch and get back to you with the test result 
later.

Since this patch is in the kernel, it will affect others (but it will be 
fine if this patch only applies to zybo-linux-bd-zynq7). Did you see the 
similar issue with TRD design? I am more interest to know if this issue 
is zybo only or not.

best regards,

Jason
