My Acer Aspire One have a hard time recognizing the SD card. I followed the Arch Wiki's Acer Aspire One Card Reader section which didn't work for my model NAV50. System log:

Any ideas, anyone?

I think I have slightly reduced the problem. First I reformatted the card from EXT4 to VFAT. Then I switched from kernel ck-atom 3.14.6 to LTS 3.10.43 and I/O Scheduler from BFQ back to deadline. Now the SD card is able to be mounted 3/5 times but still not on startup.
