Texas Instruments PCIxx12 Cardbus Controller

Question

Hello guys. I have a trouble with this subject on Arch Linux. Using latest 3.0 kernel and 4 GB SD card. This card is perfectrly works on Ubuntu 11.04 and Windows 7 - so it is not hardware problem.
My lspci -v
0f:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)
Subsystem: Acer Incorporated [ALI] Device 011f
Flags: bus master, medium devsel, latency 57, IRQ 22
Memory at fc101000 (32-bit, non-prefetchable) [size=4K]
Capabilities: <access denied>
Kernel driver in use: tifm_7xx1
Kernel modules: tifm_7xx1
0f:06.3 SD Host controller: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller
Subsystem: Acer Incorporated [ALI] Device 011f
Flags: bus master, medium devsel, latency 57, IRQ 22
Memory at fc102800 (32-bit, non-prefetchable) [size=256]
Capabilities: <access denied>
Kernel driver in use: sdhci-pci
Kernel modules: sdhci-pci
Some dmesg messages when I insert card:
$ dmesg | grep mmc

Can someone help me?

Answer 1

The  tifm_* drivers are marked as EXPERIMENTAL even in the 3.* kernel; so not too shocked to see a problem.
This line:
   [  306.673697] mmc1: error -123 whilst initialising SD card
makes me think that the mmc subsystem doesn't even recongnise that there's even a card inserted since that appears to equate to the following errno:
   #define ENOMEDIUM       123     /* No medium found */
You might need to take this to the kernel folks.
Oh... a suggestion.
You get extra points for including the kernel log snippet, but you got points subtracted by just posting "grep" snippets of it. The order that the kernel executes... and therefore the order of the kernel log entries... is very important... and you messed up that order in the logs. For instance if you look again at the "real" kernel log, you'll see where the code path goes from tifm_core, to the mmc code, and then to the tifm_sd code... so order is important.
Instead attempt to include "blocks" of kernel log snippets... especially if it's something under your control... such as inserting a SD card
