Description:
Recognizing of any SD Card fails by SD Host controller: O2 Micro, Inc. Device 8520 (rev 01) Additional info: * package version(s) linux 3.12.8-1 linux-api-headers 3.12.4-1 linux-firmware 20131230.52d77db-1 linux-headers 3.12.8-1 * config and/or log files etc. # dmesg | grep mmc [ 2.412190] mmc0: Unknown controller version (3). You may experience problems. [ 2.412219] mmc0: Hardware doesn't specify timeout clock frequency. # lspci 11:00.0 SD Host controller: O2 Micro, Inc. Device 8520 (rev 01) Steps to reproduce: According to Adam Lee from Canonical this bug can be reproduced with the following hardware: Card readers on Lenovo ThinkPad W540, Dell Latitude E5440 and Dell Latitude E6540 don't work without this patch. My own mobile computer is a Dell Precision M6800. Patch for mmc-next already written: http://article.gmane.org/gmane.linux.kernel.mmc/24244 See also Bug Report on Launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1239938 |
This task depends upon
If wanted I can deliver the diff between 3.12 and 3.14.
Same dmesg error as in original post, and SD cards do not get recognised
I've got a Dell E6540

these commands should allow you to use your SD-Card, according to 0xf8.org [1]:
rmmod sdhci sdhci_pci sdhci_acpi
modprobe sdhci debug_quirks2="0x4"
modprobe sdhci_pci
However, there is also an issue under kernel.org [1], which notes that instead
of "0x4", the value of debug_quirks2 should be set to "0x10000".
Hope this is useful :)
