Public bug reported: When inserting an SDHC card into the Ricoh e823 card reader on my Thinkpad T420s, the card is not mounted and the block device is never created. There is a similar bug #773524, but the workaround provided there and the updated kernel version haven't solved my problem. I would love to help get this solved and am willing and able to test various solutions.
In dmesg, I see "mmc0: error -110 whilst initialising SD card" after inserting the card. tom@whaam ~ $ sudo lspci -v -d 1180:e823 05:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 07) Subsystem: Lenovo Device 21d2 Flags: bus master, fast devsel, latency 0, IRQ 10 [virtual] Memory at d0d00000 (32-bit, non-prefetchable) [size=256] Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [78] Power Management version 3 Capabilities: [80] Express Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [800] Advanced Error Reporting Kernel driver in use: sdhci-pci Kernel modules: sdhci-pci For reference, this is what happens when I run the workaround in comment #13 on bug #773524 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773524/comments/13): Mar 26 00:04:15 whaam kernel: [ 413.265533] sdhci: Secure Digital Host Controller Interface driver Mar 26 00:04:15 whaam kernel: [ 413.265535] sdhci: Copyright(c) Pierre Ossman Mar 26 00:04:15 whaam kernel: [ 413.271153] sdhci-pci 0000:05:00.0: SDHCI controller found [1180:e823] (rev 4) Mar 26 00:04:15 whaam kernel: [ 413.271232] sdhci-pci 0000:05:00.0: found PCI INT A -> IRQ 10 Mar 26 00:04:15 whaam kernel: [ 413.271241] sdhci-pci 0000:05:00.0: sharing IRQ 10 with 0000:00:16.3 Mar 26 00:04:15 whaam kernel: [ 413.271256] sdhci-pci 0000:05:00.0: sharing IRQ 10 with 0000:00:1c.3 Mar 26 00:04:15 whaam kernel: [ 413.271757] sdhci-pci 0000:05:00.0: setting latency timer to 64 Mar 26 00:04:15 whaam kernel: [ 413.271793] mmc0: no vmmc regulator found Mar 26 00:04:15 whaam kernel: [ 413.271832] Registered led device: mmc0:: Mar 26 00:04:15 whaam kernel: [ 413.272094] mmc0: SDHCI controller on PCI [0000:05:00.0] using DMA Mar 26 00:05:08 whaam kernel: [ 465.984670] mmc0: error -110 whilst initialising SD card Mar 26 00:05:08 whaam kernel: [ 466.439245] mmc0: error -110 whilst initialising SD card Mar 26 00:05:09 whaam kernel: [ 466.614932] mmc0: error -110 whilst initialising SD card Mar 26 00:05:09 whaam kernel: [ 466.777559] mmc0: error -110 whilst initialising SD card Mar 26 00:05:09 whaam kernel: [ 466.946194] mmc0: error -110 whilst initialising SD card Mar 26 00:05:09 whaam kernel: [ 467.115316] mmc0: error -110 whilst initialising SD card Mar 26 00:05:09 whaam kernel: [ 467.290641] mmc0: error -110 whilst initialising SD card Additional info: tom@whaam ~ $ cat /proc/version_signature Ubuntu 3.0.0-16.29-generic 3.0.20 ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/965280 Title: Thinkpad T420s - Ricoh e823 not working with SDHC cards (11.10) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/965280/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
