Hi, I discovered this by chance. The SD card reader in my laptop has never worked, but now I noticed it does after suspending and resuming. The controller is probed and attached on boot: sdhci_acpi1: <Intel Bay Trail/Braswell SDXC Controller> iomem 0x90a00000-0x90a00fff irq 47 on acpi0 But nothing happens if I put a card in. Unless I suspend and resume: mmc1: <MMC/SD bus> on sdhci_acpi1 mmcsd0: 32GB <SDHC SL32G 8.0 SN 19CD02C0 MFG 11/2014 by 3 SD> at mmc1 50.0MHz/4bit/65535-block Then I can remove and replug cards and it seems to work just fine. Jakob
