I don't know why that happens, but my first thought was that there's a problem with the SDIO bus. On what platform are you testing this? Can you slow down the SDIO bus just to test if that helps? I haven't tested SD45 myself, so this can be also SD45 specific problem. Can you enable full logs (0xffffffff) so that we can see packet contents?
