This is the first data request. 512 bytes reading. It was finished successfully: command end + data end = 3.

But here is the problem. For some reason you have _zero_ data size. Controller reports successful competition, but it probably isn't

Nov 6 20:21:11 maggie kernel: sdhci_request cmd op 17 arg 0 flags 53 data 0 Nov 6 20:21:11 maggie kernel: sdhci0-slot0: got interrupt 18002 Nov 6 20:21:11 maggie kernel: sdhci0-slot0: Command error 1 (opcode 17 arg 0

there is no active command.

Here is the results of the previous. Card still sending something, does not responds to the command, controller signals error.

# fdisk /dev/mmcsd0

flags 53 dlen 0 dflags 2)

Here is just the same. And you have exactly the same with PIO mode. So looks like it is not card or driver problem, but sooner, mmc or mmcsd layer problem and it looks quite strange. Which sources exactly do you have, are they latest, are they in sync with each other and have you rebuilt all of them carefully?

If so, you can try to uncomment // printf("Len %d %lld-%lld flags %#x sz // ... lines in mmcsd.c to look what happens.

Sorry for the lengthy mail :)

Thanks, I like such mails, it's like a hunting. :)
