Драйвер некорректно определяет деления базовой частоты; при базовой частоте ниже, чем искомая частота.
некорректное определение значений для MMIO[02Ch] "SDCLK Frequency Select"
Система "не увидела" SD-карту. SD-карта выжила, полностью работоспособна в др. системах.

en---
The driver does not correctly determine the base frequency divisions; when the base frequency is lower than the desired frequency.
incorrect definition of values for MMIO[02Ch] "SDCLK Frequency Select"
The system "did not see" the SD card. The SD card has survived and is fully functional in other systems.
