Chris Looking at c59d44739a8519cb7abdcd7cb7fd88f807dec9fd (mmc: card: Use manufacturer ID symbols in card quirks.) you set Sandisk card manufacturer ID at 0x2, but in https://www.jedec.org/standards-documents/docs/jep-106ab and actual SEM16G eMMC, the manufacturing code is 0x45. localhost device # cat name SEM16G localhost device # cat manfid 0x000045 Andrei, Does the fix (6a7a6b45f454686a1549729bfbae31f0b3b595d6) for SEM16G applies to a very specific model with different CID manfid or do we need to upgrade drivers/mmc/core/quirks.h to really apply the quirks to SEMxxG devices?
