Waiting for root device /dev/mmcblk0p1... mmc1: host does not support reading read-only switch. assuming write-enable. mmc1: new high speed SDHC card at address b368 mmcblk0: mmc1:b368 SDC 3.74 GiB mmcblk0: p1 mmc1: Timeout waiting for hardware interrupt. mmcblk0: error -110 transferring data, sector 3678224, nr 40, cmd response 0x900, card status 0xc00 end_request: I/O error, dev mmcblk0, sector 3678225 Buffer I/O error on device mmcblk0p1, logical block 458754 lost page write due to I/O error on mmcblk0p1 This patch fixes the problem by lowering the usdhc clock and correcting watermark configuration.
