That doesn't sound good at all. If you ever see juddery or noisy screen
thing then SD Card communication is totally corrupted.
It's juddering about because of problems with Glamo DRAM, all SD Card
communication goes through that DRAM and is similarly "juddered" or
I've seen the same thing at various times due to not yet understood
collection of problems with Glamo memory bus. We (olv) worked around it
by cranking up bus wait states which seems to have been pretty
effective, however I still see madness from it on resume on 2.6.26.
Have you seen this screen corruption thing before or is this the first time?
