I think, that we can't be 100% sure that these two problems are not related
at all. If some changes to VIC/ep93xx interrupt handling etc will be send
to list, I'll test them in my configuration without my patch. If it will
help (to fix the problem I'm observing also in 3.2), then double buffering
for M2M could be much simplier.
Now, I'm trying to test mmc_spi in ep93xx and let you know what the results
are.
