Randy Syring, the next step would be to install Ubuntu to another partition with default settings (i.e. no out-of-tree modules) if you need to preserve the original install.
Once this is in place, at your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: xenial -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1531653 Title: Macbook Pro Retina 11,1 SD Card Reader Doesn't Work Status in linux package in Ubuntu: Incomplete Bug description: I have a Macbook Pro (MBP) Retina 11,1 with an SD card reader that will not work. The SD card reader: * has device code 05ac:8406 * does work in OS X. * does not work in SystemRescueCD running kernel 3.14.56-std461-amd64 - I have a friend with an identical Macbook Pro and his SD card reader does work in SystemRescueCD * Does not show up in lsusb * Does not display any messages in dmesg when an SD card is inserted * Device 05ac:8406 does not show up in dmesg * Does not work in kernel 4.2.0-22.27~14.04.1. All issues reported here seem to be the same regardless if I use 3.13 or 4.2. * Uses the following drivers on my friends MBP: sd, usb-storage, usb, xhci_hcd The last point made me look closer at the xhci_hcd logs: rsyring@loftex:~$ dmesg | grep xhci_hcd [ 2.681478] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 2.681498] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 1 [ 2.681589] xhci_hcd 0000:00:14.0: cache line size of 256 is not supported [ 2.681607] xhci_hcd 0000:00:14.0: irq 63 for MSI/MSI-X [ 2.681755] usb usb1: Manufacturer: Linux 3.13.0-57-generic xhci_hcd [ 2.682098] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 2.682115] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 2 [ 2.682219] usb usb2: Manufacturer: Linux 3.13.0-57-generic xhci_hcd [ 3.980423] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd [ 9.352422] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 14.560476] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 20.549170] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 25.757227] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 26.129482] usb 1-1: new high-speed USB device number 2 using xhci_hcd [ 26.321707] usb 1-3: new full-speed USB device number 3 using xhci_hcd [ 26.505802] usb 1-5: new full-speed USB device number 4 using xhci_hcd [ 26.603224] usb 2-1.1: new SuperSpeed USB device number 6 using xhci_hcd [ 26.754245] usb 1-1.2: new low-speed USB device number 5 using xhci_hcd [ 26.954315] usb 1-1.4: new low-speed USB device number 6 using xhci_hcd [ 27.050323] usb 1-3.1: new full-speed USB device number 7 using xhci_hcd [ 27.142383] usb 1-3.2: new full-speed USB device number 8 using xhci_hcd [ 27.234476] usb 1-3.3: new full-speed USB device number 9 using xhci_hcd [ 81.685139] usb 1-1.4: new low-speed USB device number 10 using xhci_hcd The "Timeout while waiting" messages are suspicious to me. dmesg on my friend's MBP does not show those messages.
