That's odd that one card works and one doesn't. Is that repeatable, or does your card reader just sometimes fail to detect the card, and it was just chance that one card didn't work? I saw a mention in a mailing list message of a card reader that only supported one voltage, unlike some others that support 2 or more. So maybe some cards aren't compatible with some readers. I don't know.
Also see https://wiki.ubuntu.com/DebuggingHardwareDetection In this case, there's obviously no USB involved, but the full kernel uname and version signature never hurt. Most useful would be lspci -vvnn, since these SD card reader problems are almost always chipset- specific, and the sdhci lines from your dmesg output don't say what the hardware is. Wouldn't hurt do include the full dmesg output, too. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- kernel - problem with sd card recognition https://bugs.launchpad.net/bugs/300845 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
