Title:
[ACER V5-171] SD card reader not working
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Tested card was a 64GB SDXC from supertalent and Lexar 16GB SDHC.
In both cases nothing happens when cards are inserted, and after
10seconds dmesg shows: "mmc0: Timeout waiting for hardware interrupt."
This seems to be a common problem in ubuntu with the Broadcom
Corporation BCM57765/57785 SDXC/MMC Card Reader.
This was using ubuntu 14.04 with 3.13.0-32-generic #57-Ubuntu SMP
I also tried the newest daily build (6th august) of the 3.16 kernel(utopic),
no change in results.
The bios is the newest version V2.21, I have earlier been told to use
the newer 2.25, however, there is no such BIOS version and 2.21 is the
newest posted on the acer webspace.
