Hi Kobayashi-san > After applying this patch on kzm9g board, I got this error regarding eMMC. > I think this is another problem. Hmm... How can I reproduce it ? It doesn't happen on my board.

Hi Moromoto-san In my case this problem occurs once per 2 or 3 times, not every time. I'm using v3.5rc2 + sh7a30-irq-fixup-patch. I tried 2 kzm9g boards. One of them is almost same as yours.
