Current mainline has (still) this problem, too. Is there any change to get this patch into 2.6.35 before the release?You should bug David Woodhouse about this.The imx NAND driver does throw this unbalanced IRQ warning in the current 2.6.35-rcX mainline tree. David can you try to get this into mainline before the release?
2.6.35-rc6 has this problem, any change to get this patch merged before the release? Marc
