Here's my patch to attempt to fix this issue, could you all give it a try please? So far it has worked for me, I'd like to hear what Nathan's dsp test case does! Basically it's modified patch from Russell, except reading back the revision register is not enough. Looks like we need to read back the same register we're writing. I guess the L3/L4 is finer grained than ARM memory attributes? Regards, Tony
