dmesg: mmcblk0: error -123 sending status command

Hello!

I have the following gentoo-kernel:
genkernel-x86-2.6.37-gentoo-r4 (with gentoo's default config)
and the following controller:
Texas Instruments PCI7420/7620 Combo CardBus, 1394a-2000 OHCI and SD/MS-Pro Controller

When I insert an SD-card in my reader then I get this in syslog:
tifm_core: MMC/SD card detected in socket 0:0
mmc0: new SD card at address 1234
mmcblk0: mmc0:1234 SD01G 972 MiB
mmcblk0: p1

I can mount the card but if I try to read some files from it I get this in syslog:
Jul 15 12:40:54 consystor6 klogd: mmcblk0: retrying using single block read
Jul 15 12:40:54 consystor6 klogd: mmcblk0: error -123 sending status command

Jul 15 12:40:54 consystor6 klogd: mmcblk0: p1

After that the card is unmounted as you can see in the log - so I can't read any data.
Same with genkernel-x86-2.6.38-gentoo-r1 (and an own config).
The SD-card works in the same system under windows without any problems.
Can anybody help me?

Best regards!

do you have the right drivers for the MMC controller in your kernel, if so are they modules or built in? if built in try as modules, that worked for me, although i had a bitch of a time as my reader is sd and xd, and xd requires a few other options in the kernel

Hello and thanks for your answer!

lspci -vv lists this:
03:04.3 Mass storage controller: Texas Instruments PCI7420/7620 Combo CardBus, 1394a-2000 OHCI and SD/MS-Pro Controller
Subsystem: Wistron Corp. Device 3006
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 57 (1750ns min, 1000ns max), Cache Line Size: 32 bytes
Interrupt: pin D routed to IRQ 22
Region 0: Memory at d2014000 (32-bit, non-prefetchable) [size=4K]
Capabilities: <access denied>
Kernel driver in use: tifm_7xx1

So the used driver is tifm_7xx1 - I don't know which other driver I could use for my card reader.
In gentoo's default config the driver is built as module. In my config it's built in.
There's no difference between "built in" or "built as module".

Now I'm building 2.6.39-gentoo-r3 with also built in tifm and that's the config:
grep MMC 2.6.39-gentoo-r3-2011-07-15-01
CONFIG_MMC=y
# CONFIG_MMC_DEBUG is not set
# CONFIG_MMC_UNSAFE_RESUME is not set
# CONFIG_MMC_CLKGATE is not set
# MMC/SD/SDIO Card Drivers
CONFIG_MMC_BLOCK=y
CONFIG_MMC_BLOCK_MINORS=8
CONFIG_MMC_BLOCK_BOUNCE=y
# CONFIG_MMC_TEST is not set
# MMC/SD/SDIO Host Controller Drivers
CONFIG_MMC_SDHCI=y
# CONFIG_MMC_SDHCI_PCI is not set
# CONFIG_MMC_SDHCI_PLTFM is not set
CONFIG_MMC_WBSD=m
CONFIG_MMC_TIFM_SD=y
# CONFIG_MMC_SDRICOH_CS is not set
# CONFIG_MMC_CB710 is not set
# CONFIG_MMC_VIA_SDMMC is not set
# CONFIG_MMC_USHC is not set

Later I will see if there's a difference...

I have found that sometimes drivers have to be built as modules, my TV card sorted that out for me, if i compiled in the drivers the card was never seen, as soon as i put them as modules it was. Not on my linux box so i cant post what my config and options selected were, when i have time i will jump right on it

As I wrote it also doesn't work when I build the MMC stuff as modules.
The controller is recognized and the drivers are loaded without errors automatically.
When I plug in my SD-card then I can mount it but a correct file transfer isn't possible.
Also with 2.6.39-gentoo-r3 I get the errors above. Maybe it's a driver bug?

quite possibly, I have Ricoh card reader and i can transfer from SD and XD, you could try looking on the bug tracker

OK, I've looked in the kernel bugzilla and I've found no similar problems.
First of all I will build vanilla-sources-2.6.39.3 (newest stable) and try the same.
If the problem is also present with this one then I think I'll ask in the linux-mmc mailing list before I post a bug in the bugzilla.
Many thanks again for your answers!
