Subject: 2.6.24 not recognizing 2G MMC card?
Date: Wed, 21 May 2008 13:21:04 -0400	[thread overview]
Message-ID: <20080521172104.GC2592@fieldses.org> (raw)

Please forgive a somewhat naive question--I'm not sure how to go about
debugging this kind of thing:

I have a Dell 1420n with card readers reported by lspci as:

03:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22)
03:01.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 12)

I have a 512MB MicroSD card which seems to be recognized fine, but a 2GB
MMC card is not.

I'm using a stock Ubuntu 8.04 kernel, which reports itself as
2.6.24-16-generic.

Skimming through commits to drivers/mmc,
5ae70296c85f96a9969891d9de3410ebdf210b71 "mmc: Disabler for Ricoh MMC
controller", looks relevant, but seems to be included in 2.6.24.

Anything I should try?  Thanks in advance for any suggestions.
