Usually it was 1-bit bus instead of 4-bit bus or no high speed timing for cards that support high speed timing. It worked although not at maximum performance. With this problem gone new bug revealed - some cards stop responding when SDHCI is switched to high speed timing mode. Me and Ian looking into it.
