Bug 297006 – sys-kernel/gentoo-sources-2.6.32 SD/MMC reader stopped working

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Doron Fediuck 2009-12-15 08:33:16 UTC]

Hi, 
I have a Lenovo W500 with a Ricoh card reader: 

15:00.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) 
15:00.3 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev ff) 
15:00.4 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 11) 
15:00.5 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 11) 


So far, using the built-in kernel drivers everything worked like a charm. Today I noticed it stopped working (I'm currently using .6.32-gentoo kernel). Relevant modules: 

sdhci_pci               5989  0 
sdhci                  14724  1 sdhci_pci 
mmc_core               53050  1 sdhci 
ricoh_mmc               3208  0

Can you attach us a copy of your dmesg?

Unfortunately there's nothing in dmesg, but I managed to
dig the following lines from my kernel log:

I'll try to unload & load the module. If it helps I'll update here.

Hi guys,
After playing with the modules it started
making some happy noises. So I rebooted and now
it works.

Sorry I bothered you. Closing this bug.
