詳細
Some SD cards have problems under Linux. Tested in arm-3.0-wip as of today with no CONFIG_MMC_UNSAFE_RESUME (to workaround #11353).
Upon insertion we get
Nov 14 19:55:16 xo-6d-81-67 kernel: [ 122.196331] sdhci: Switching to 1.8V signalling voltage failed, retrying with S18R set to 0 Nov 14 19:55:16 xo-6d-81-67 kernel: [ 122.207096] mmc0: error -84 whilst initialising SD card
The same SD card works correctly for a basic test (dir ext:) in the same unit under OFW.
The same SD card works correctly on a USB-SD card reader.
The same SD card fails identically on my Lenovo Thinkpad running Fedora's 2.6.40.6-0.fc15.x86_64 kernel.
