mb74, as per http://www.asrock.com/mb/AMD/970%20Extreme4/?cat=Download&os=BIOS an update is available for your BIOS (2.60). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-2.60 ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/1093791 Title: xhci_hcd fails detecting SD-cards Status in “linux” package in Ubuntu: Incomplete Bug description: I've got a multi card reader in my PC connected to an USB 3.0 slot. When I plug in an SD-card and copy some pictures from my SD-card to the local drive, everything works fine. But when I remove the SD-card and plug in the same or any other SD-card no device/drive is detected. The syslog only shows the following output: Dec 26 13:20:50 bender kernel: [ 1691.981335] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 3 with no TDs queued? Dec 26 13:20:50 bender kernel: [ 1691.981409] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 2 with no TDs queued? Dec 26 13:20:50 bender kernel: [ 1691.981488] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 0 with no TDs queued? Dec 26 13:20:50 bender kernel: [ 1692.085341] xhci_hcd 0000:03:00.0: WARN Event TRB for slot 1 ep 0 with no TDs queued? Interestingly USB sticks are still detected on the same USB 3.0 port, but SD-cards not. To be able to detect SD-cards again I have to reboot the PC. This bug only shows up when I copy some files. When I only plug in and remove SD-cards several times this bug does not occur. For me it seems to be a bug in the data transfer code for SD-cards.
