If I force PIO mode (sdhci.debug_quirks=0x60), I get: [ 111.201763] mmc0: Timeout waiting for hardware interrupt. [ 111.201887] mmc0: Got data interrupt 0x00000020 even though no data operation was in progress. [ 111.202032] mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0x400e00 And enabling SDHCI_QUIRK_NO_MULTIBLOCK (sdhci.debug_quirks=0x200000) seems to fix all immediate issues, but it also degrades the performance seriously. /Timo -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
