The poky UI comes up fine if the filesystem is in NAND or NFS, while with MMC it gives errors like segmentation faults/syntax error while there are none. Seems like read from MMC is getting corrupted. I tried the 4 tests which are available as part of mmc_test for highmem, all of them seem to PASS. Wanted to get inputs if there are any known issues with MMC block layer handling highmem pages. Thanks Hemanth
