SD Card reader on a Thinkpad T520 lspci: 0d:00.0 System peripheral: Ricoh Co Ltd MMC/SD Host Controller (rev 05) kernel: 3.4.4-4.fc16.x86_64 Card is a Samsung 32GB MicroSD in an SD adapter. Tried with two different adapters - same result. Mounted the card via USB adapter, no problem. Lots of errors like this: Jul 26 19:53:30 nitai kernel: [66948.748184] end_request: I/O error, dev mmcblk0, sector 439791 Jul 26 19:53:30 nitai kernel: [66948.748445] mmcblk0: error -84 sending status command, retrying Jul 26 19:53:30 nitai kernel: [66948.748479] mmcblk0: error -84 sending status command, retrying Jul 26 19:53:30 nitai kernel: [66948.748506] mmcblk0: error -84 transferring data, sector 439792, nr 2, cmd response 0x900, card status 0x0 Jul 26 19:53:30 nitai kernel: [66948.748508] end_request: I/O error, dev mmcblk0, sector 439792 Jul 26 19:53:30 nitai kernel: [66948.748771] mmcblk0: error -84 sending status command, retrying Jul 26 19:53:30 nitai kernel: [66948.748797] mmcblk0: error -84 transferring data, sector 439793, nr 1, cmd response 0x900, card status 0x0 Jul 26 19:53:30 nitai kernel: [66948.748802] end_request: I/O error, dev mmcblk0, sector 439793 Jul 26 19:53:36 nitai kernel: [66954.495338] mmcblk0: error -110 transferring data, sector 4321650, nr 8, cmd response 0x900, card status 0xc00 Jul 26 19:53:36 nitai kernel: [66954.495418] end_request: I/O error, dev mmcblk0, sector 4321651 Jul 26 19:53:36 nitai kernel: [66954.855036] mmcblk0: response CRC error sending r/w cmd command, card status 0x800e00 Jul 26 19:53:36 nitai kernel: [66954.855104] mmcblk0: error -84 sending status command, retrying Jul 26 19:53:36 nitai kernel: [66954.855128] mmcblk0: timed out sending r/w cmd command, card status 0xe00 Jul 26 19:53:36 nitai kernel: [66954.855186] mmcblk0: timed out sending r/w cmd command, card status 0x400e00 Jul 26 19:53:36 nitai kernel: [66954.855244] mmcblk0: timed out sending r/w cmd command, card status 0x400e00 Jul 26 19:53:36 nitai kernel: [66954.855301] mmcblk0: timed out sending r/w cmd command, card status 0x400e00 Jul 26 19:53:36 nitai kernel: [66954.855357] mmcblk0: timed out sending r/w cmd command, card status 0x400e00 Jul 26 19:53:36 nitai kernel: [66954.855360] end_request: I/O error, dev mmcblk0, sector 431475 Jul 26 19:53:36 nitai kernel: [66954.855363] Buffer I/O error on device mmcblk0p2, logical block 19827 Jul 26 19:53:36 nitai kernel: [66954.855365] lost page write due to I/O error on mmcblk0p2 Jul 26 19:53:36 nitai kernel: [66954.954944] mmcblk0: response CRC error sending r/w cmd command, card status 0x800b00
I'm facing similar errors with Kernel-3.6.0-rc4 on a t430s. To reporduce: 1. cp 2. sync -> errors in dmesg
See bug #871638 for the fix
