So IMO, no rush to fix for 2.6.29-rc ... > It's also to difficult to test in our H/W since it's configured only > support 3.0V. Easily tested with a Beagle or SDP though, if you have a 1.8V or dual-voltage card (maybe RS-MMC, as for an N770 tablet). > How about to separate it two phases, first fix the mmc suspend/resume > works again, and then verify dual voltage if there are these hardware Well, two patches for sure; I don't know that the order will matter. I just sent a patch fixing that code in the current OMAP git tree, which has some fixes that are scheduled to merge for 2.6.30-rc. - Dave
