I had a few reported CRC issues on our msm8960 based devices, but thinks seems functionally "ok". On APQ8064, the kernel finds the onboard eMMC and when mounting it I get the following: [ 1.624118] mmc0: new high speed MMC card at address 0001 [ 1.627521] mmcblk0: mmc0:0001 MAG2GA 14.5 GiB [ 1.632714] mmcblk0boot0: mmc0:0001 MAG2GA partition 1 2.00 MiB [ 1.636989] mmcblk0boot1: mmc0:0001 MAG2GA partition 2 2.00 MiB [ 1.637393] Freeing unused kernel memory: 332K (c09c6000 - c0a19000) [ 1.663379] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 1.663659] mmcblk0: error -84 transferring data, sector 30535648, nr 8, cmd response 0x900, card status 0xb00 [ 1.669851] mmcblk0: retrying using single block read [ 1.681534] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 1.686758] mmcblk0: p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 p13 p14 p15 p16 p17 p18 p19 p20 p21 p22 p23 p24 p25 p26 mkdir: can't create directory '/dev': File exists [ 1.712644] mmcblk0boot1: unknown partition table [ 1.717419] mmcblk0boot0: unknown partition table [ 2.255625] EXT3-fs (mmcblk0p24): error: couldn't mount because of unsupported optional features (40) [ 2.256687] EXT2-fs (mmcblk0p24): error: couldn't mount because of unsupported optional features (40) [ 2.277945] mmcblk0: error -84 transferring data, sector 160824, nr 232, cmd response 0x900, card status 0xb00 [ 2.277985] mmcblk0: retrying using single block read [ 2.288518] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.292914] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.300985] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.311787] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.316151] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.322986] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 2.329640] end_request: I/O error, dev mmcblk0, sector 160853 [ 2.337266] end_request: I/O error, dev mmcblk0, sector 160856 [ 2.343093] end_request: I/O error, dev mmcblk0, sector 160864 [ 2.348826] end_request: I/O error, dev mmcblk0, sector 160872 [ 2.354720] end_request: I/O error, dev mmcblk0, sector 160880 [ 2.360458] end_request: I/O error, dev mmcblk0, sector 160888 [ 2.366346] end_request: I/O error, dev mmcblk0, sector 160896 [ 2.372175] end_request: I/O error, dev mmcblk0, sector 160904 [ 2.377906] end_request: I/O error, dev mmcblk0, sector 160912 [ 2.383802] end_request: I/O error, dev mmcblk0, sector 160920 [ 2.393204] EXT4-fs (mmcblk0p24): mounted filesystem with ordered data mode.
