I have the same problem on an Acer Aspire V5-171, same broadcomm hardware BCM57765, same log messages, kubuntu 12.10, kernel 3.5.0-21.
I might open another bug if necessary, but I can't add much more. Also, this link gives some more logs with CONFIG_MMC_DEBUG=y and mentions some hardware specificity (private mmio-block) as the root of the problem: http://www.spinics.net/lists/linux-mmc/msg08483.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067222 Title: 14e4:16bc Built-in SD card reader on Acer Aspire One AS756 intermittently operative To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1067222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
