Some relevant stuff from one of the boots, but definitely seems like some voltage switching not going well: [ 1.450613] sdhci_msm 7864900.sdhci: Got CD GPIO [ 1.460379] sdhci_msm 7864900.sdhci: Failed getting OCR mask: 0 [ 1.462862] l11: voltage operation not allowed [ 1.465097] sdhci_msm 7864900.sdhci: could not set regulator OCR (-1) [ 1.469684] mmc0: MAN_BKOPS_EN bit is not set [ 1.476456] l12: voltage operation not allowed [ 1.480527] mmc1: Switching to 3.3V signalling voltage failed [ 1.484909] l12: voltage operation not allowed [ 1.490674] mmc1: Switching to 1.8V signalling voltage failed [ 1.495058] l12: voltage operation not allowed [ 1.500817] mmc1: Switching to 1.2V signalling voltage failed [ 1.507342] mmc0: new HS200 MMC card at address 0001 [ 1.515354] mmcblk0: mmc0:0001 DS2008 7.28 GiB [ 1.520125] mmcblk0boot0: mmc0:0001 DS2008 partition 1 4.00 MiB [ 1.524369] mmcblk0boot1: mmc0:0001 DS2008 partition 2 4.00 MiB [ 1.530288] mmcblk0rpmb: mmc0:0001 DS2008 partition 3 4.00 MiB [ 1.533864] mmc1: SDHCI controller on 7864900.sdhci [7864900.sdhci] using ADMA 64-bit [...] [ 1.614109] mmc1: error -110 whilst initialising SD card [ 1.716226] mmc1: Reset 0x1 never completed.
