SD reader won't work: mmc0 errors

I've got this integrated SD card reader in my laptop:

14:00.1 SD Host controller: O2 Micro, Inc. Device 8120 (rev 01) (prog-if 01)
    Subsystem: Dell Device 02eb
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at f0802000 (32-bit, non-prefetchable) [size=256]
    Capabilities: <access denied>
    Kernel driver in use: sdhci-pci
    Kernel modules: sdhci-pci

and it just doesn't want to work with me.  Dmesg gives me this error message:

mmc0: Unexpected interrupt 0x02000000.

mmc0: error -110 whilst initialising SD card

I have run out of ideas, so if you have one please let me know, and if you need more info let me know.

Re: SD reader won't work: mmc0 errors

Have the exact same problem in gentoo (same dmesg error etc.), with a dell latitude E6410ATG.

Let me know if you've solved this.

Re: SD reader won't work: mmc0 errors

Same error here with a Dell Precision M4500 in Arch x86_64
