** Description changed: Under ubuntu 15.10 I can't use my Sandisk ultra 64GB microSD (with a SD card adapter) with the built in SD card reader. I seem to be getting the following errors. [ 1268.126602] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock [ 1268.128381] mmc0: tuning execution failed [ 1268.128386] mmc0: error -5 whilst initialising SD card [ 1268.554319] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock [ 1268.556098] mmc0: tuning execution failed [ 1268.556103] mmc0: error -5 whilst initialising SD card [ 1268.993995] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock [ 1268.995778] mmc0: tuning execution failed [ 1268.995786] mmc0: error -5 whilst initialising SD card [ 1269.453666] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock [ 1269.455449] mmc0: tuning execution failed [ 1269.455458] mmc0: error -5 whilst initialising SD card It was working fine under vivid with kernel 3.19. Went through all the kernels from 3.19 to 4.2 (http://kernel.ubuntu.com /~kernel-ppa/) and found out that until 4.1.8-040108-generic the SD card reader would play fine and only after I put 4.1.9 and on I started getting the errors. + WORKAROUND: rmmod sdhci sdhci_pci sdhci_acpi + modprobe sdhci debug_quirks2="0x10000" + modprobe sdhci_pci + ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-19-generic 4.2.0-19.23 ProcVersionSignature: Ubuntu 4.2.0-19.23-generic 4.2.6 Uname: Linux 4.2.0-19-generic x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC2: alex 1606 F.... pulseaudio - /dev/snd/controlC0: alex 1606 F.... pulseaudio - /dev/snd/controlC1: alex 1606 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC2: alex 1606 F.... pulseaudio + /dev/snd/controlC0: alex 1606 F.... pulseaudio + /dev/snd/controlC1: alex 1606 F.... pulseaudio CurrentDesktop: Unity Date: Sun Dec 6 01:40:18 2015 HibernationDevice: RESUME=UUID=acf75838-59f9-4461-9fe4-e9bdf33b28be InstallationDate: Installed on 2015-10-27 (38 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: Dell Inc.
