I had this problem with a Kingston 4GB card. There was a kernel patch a couple of weeks ago that seemed to solve this, although given the intermittent nature of the problem I may just have been unusually lucky. I've been using other cards since so can't give a longer term test report. It's in Andy's stable tree, but last I heard it was only in the unstable OM feed. I don't know which patch set Debian uses. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
