Hello, So I compiled and tried the updated module.
I tried outright replacing the existing sdhci-pci module and rebooting, to see how it behaves under that circumstance. When I do that, I don't get the "Ricoh E823 MMC detected, slowing down the bus" string, and so the reader doesn't work (old behavior where it says "error -110 whilst initialising"). I then rebooted, removed the module and reinserted it, and I get this in dmesg: [ 361.638355] sdhci-pci 0000:01:00.0: PCI INT A disabled [ 365.436461] sdhci-pci 0000:01:00.0: SDHCI controller found [1180:e823] (rev 4) [ 365.436551] sdhci-pci 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 365.436560] Ricoh E823 MMC detected, slowing down the bus [ 365.436895] sdhci-pci 0000:01:00.0: setting latency timer to 64 [ 365.436912] mmc0: no vmmc regulator found [ 365.437051] Registered led device: mmc0:: [ 365.437237] mmc0: SDHCI controller on PCI [0000:01:00.0] using DMA So at least it's recognizing the reader and (hopefully) issuing the PCI commands. However I get this when I insert the card: [ 1261.775828] mmc0: card lacks mandatory switch function, performance might suffer.

I reboot, then remove that module and insert the test module. I get the same result as above, and the card doesn't work :( Just to double-check that the setpci commands from comment #13 are good, I rebooted again with the original module, unloaded sdhci and sdhci_pci, ran the commands and reloaded these two modules (originals). I don't get any errors and the cards get recognized and mounted without problems. Maybe I'm doing something wrong, if so please let me know, also let me know if I should test something else.
