I did, same error: $ sudo dd if=/dev/mmcblk0 of=/dev/null count=1 iflag=direct; sudo mmc status get /dev/mmcblk0 1+0 records in 1+0 records out 512 bytes copied, 0.000832209 s, 615 kB/s ioctl: Connection timed out Could not read response to SEND_STATUS from /dev/mmcblk0 And there's a corresponding [ 3540.312203] rtsx_pci_sdmmc rtsx_pci_sdmmc.0: __mmc_blk_ioctl_cmd: cmd error -110 in dmesg. This is on a third machine, a Dell laptop (though the SD card reader is driven by the same rtsx_pci_sdmmc driver as in the Sony case).
