Public bug reported: Upon attempting to use my SD card reader in my Thinkpad W541, I am no longer able to read cards. Ubuntu 17.10 worked OK, but 18.04 does not. I have since done a fresh install and it still does not work. I have tried some workarounds including: sudo rmmod sdhci sdhci_pci sdhci_acpi sudo modprobe sdhci debug_quirks2="0x4" sudo modprobe sdhci_pci
including: "0x10000", and "0x80000000", but none of these are working. I still cannot get my SD card reader from O2 Micro to work. The logs I am getting when inserting an SD card are the following: 7:26:36 PM kernel: mmc0: sdhci: ============================================ 7:26:36 PM kernel: mmc0: sdhci: ADMA Err: 0x00000000 | ADMA Ptr: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Host ctl2: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Resp[2]: 0x00000000 | Resp[3]: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Resp[0]: 0x00000000 | Resp[1]: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Cmd: 0x0000341a | Max curr: 0x005800c8 7:26:36 PM kernel: mmc0: sdhci: Caps: 0x25fec8bf | Caps_1: 0x10002078 7:26:36 PM kernel: mmc0: sdhci: AC12 err: 0x00000000 | Slot int: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Int enab: 0x00ff0083 | Sig enab: 0x00ff0083 7:26:36 PM kernel: mmc0: sdhci: Timeout: 0x00000000 | Int stat: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Wake-up: 0x00000000 | Clock: 0x0000fa07 7:26:36 PM kernel: mmc0: sdhci: Power: 0x0000000f | Blk gap: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Present: 0x01ff0001 | Host ctl: 0x00000001 7:26:36 PM kernel: mmc0: sdhci: Argument: 0x00000c00 | Trn mode: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Blk size: 0x00000000 | Blk cnt: 0x00000000 7:26:36 PM kernel: mmc0: sdhci: Sys addr: 0x00000000 | Version: 0x00000603 7:26:36 PM kernel: mmc0: sdhci: ============ SDHCI REGISTER DUMP =========== 7:26:36 PM kernel: mmc0: Timeout waiting for hardware cmd interrupt. 7:26:23 PM kernel: mmc0: Unknown controller version (3). You may experience problems. Any help is welcome, but I am submitting this as a bug, because it seems to be affecting all of my laptops with O2 Micro's as well, not just my Thinkpad W541 I am writing this on right now.
