[beagleboard] BB-xM sdhc error

I had issues using my pny class 10 16gb with ubuntu demo image but I also tried the super jumbo image image and worked fine speed wasn't all that much different from a standard class 2 though so this requires further iknvestigation overclocking in ubuntu helped I took it up to 1.2GHz but gets hot as hell but speed was nice

It works good with Toshbia sdhc sd cards and no problem yet
