Hello!
I have a x86 gentoo system with vanilla 2.6.39.3 kernel and a
Texas Instruments PCI7420/7620 Combo CardBus, 1394a-2000 OHCI and
SD/MS-Pro Controller
(that's what lscpi -v says).
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 these
errors in syslog:
---

After that the card is unmounted as you can see in the log - so I can't
read any files.
Same with
- genkernel-x86-2.6.37-gentoo-r4 (with gentoo's default config)
- genkernel-x86-2.6.38-gentoo-r1 (and my own config)
The SD-card works in the same system under windows without any problems.
Can anyone help me?
Best regards,
Lukas
PS:
The MMC part of my kernel config:
---
