I see this bug was tagged as expired, but this still affects me. I have a MSI M670 with O2Micro SD reader and I still can't read any memory card.
When I do dmesg | grep mmc this is the output: [ 1.970791] mmc0: Unknown controller version (16). You may experience problems. [ 1.970824] mmc0: no vmmc regulator found [ 1.970869] Registered led device: mmc0:: [ 2.016368] mmc0: SDHCI controller on PCI [0000:04:04.2] using PIO [ 3.325460] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray [39144.992060] mmc0: Timeout waiting for hardware interrupt.
