Comment # 4 on bug 899633 from Takashi Iwai

Could you give the dmesg output with openSUSE 3.16 kernel and hwinfo output?

You may try to pass debug_quirks and debug_quirks2 options to sdhci module.
The meaning of each quirk bit is found in include/linux/mmc/sdhci.h.

For example, pass shdci.debug_quirks=0x40 in boot option.
