Message-ID: <20080521172104.GC2592@fieldses.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.17+20080114 (2008-01-14) From: "J. Bruce Fields" Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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. --b.
