Bug report as per https://wiki.ubuntu.com/Bugs/Upstream/kernel, using the upstream kernel found here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc6-utopic/ [1.] One line summary of the problem: Broadcom BCM57765/57785 SDXC/MMC Card Reader doesn't work for Ultra High Speed SD cards [2.] Full description of the problem/report: As I attach my Ultra High Speed SD card (SDHC I, U1, C10, rated at 30MB/s), Linux is unable to read from it at all. I get the following output in dmesg: [ 101.498565] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock [ 101.498580] mmc0: new ultra high speed SDR104 SDHC card at address 59b4 [ 101.502161] mmcblk0: mmc0:59b4 SD32G 29.5 GiB [ 101.512251] mmc0: Controller never released inhibit bit(s).

I get the following output in dmesg when attaching the SD card while using this module parameter: [ 180.617180] mmc0: new high speed SDHC card at address 59b4 [ 180.617366] mmcblk0: mmc0:59b4 SD32G 29.5 GiB [ 180.717318] mmcblk0: p1 [ 200.640119] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. [ 314.370496] mmc0: card 59b4 removed The card is recognized and shows up in my KDE interface automatically and works like it should, although the transfer rate maxes out at an abysmal 1.25 MB/s. (NOTE: When using the downstream Ubuntu kernel I get a much more palatable 20MB/s in this situation) For reference, the hardware is capable of supplying a steady 50 MB/s, which is what I see in OS X on the same machine.

[8.] Other notes, patches, fixes, workarounds: [8.1] Workaround Use module parameter debug_quirks2=4 for the sdhci module. With this (the "upstream") kernel, I get 1.25 MB/s transfer rate and high CPU use. With the downstream Ubuntu kernel, I get 20 MB/s transfer rate and a little CPU use. With OS X, I get 50 MB/s. [8.2] Note: Ethernet controller in the same chipset Apparently, the SDHC controller comes on the same chip as an Ethernet controller. I have read some reports that people need to engage the Ethernet port in order to make the SD-reader work. However, on this hardware, the Ethernet controller is not attached to an Ethernet port. There is no Ethernet port on this machine, even though there is an Ethernet controller, as you can see in the lspci output. [8.3] Note: Excessive heat When attaching the UHS-SD card without enabling the workaround (debug_quirks2=4), the following side effects happen: a. One CPU core ends up spinning at 100% b. The machine gets really, uncomfortably, hot really quickly near the SD card slot. The SD card gets unexpectedly hot as well.
