Ok, here's my very weird problem :
I'm running ArchLinux with kernel 2.6.28 with all the latests updates and I've followed everything I could find on the Arch wiki ( http://wiki.archlinux.org/index.php/Acer_Aspire_One
Unfortunatly, my left SDHC card reader does not work with my A-Data 8GB card. The thing is, if I boot Live using Fedora, Linpus or even using Arch on a usb drive, then it works :S
When I plug it in and run "dmesg | tail", I get
mmc0: error -84 whilst initialising SD card
and no entry in /dev/ is created (normally it creates /dev/mmcblk0).
If I use any other SD card, then it work. Also, if I use my card in somebody else's laptop, it works. Using the right SD card reader results in the exact same behaviour.
Since the Aspire One's SSD is only 8GB, I kinda need that SD card to work ...
btw, forgot to mention, I've tried reformating in many different ways (e.g. : ext2, fat16, fat32, xfs) and still no results.
Anybody got an idea ?
