Can anyone test 2.6.35 kernel from 10.10 to confirm that you still have
that issue?
It was found that this controller supports DMA but doesn't tell the linux that
it does. Therefore linux would revert to using slow PIO mode (cpu runs in a
loop and read data byte after byte).
I think this causes timeouts, and one of you even noticed that increasing
timeout helps.
Btw, it contains a driver to read xD cards as well (mine :-))
I hope I will eventually write the MemoryStick driver as well.
** Changed in: linux (Ubuntu)
Status: Triaged => Incomplete
