fedora 20: sd card reader set up (with warning)

i finally needed to use the sd card reader of my dell laptop and found out that it was not set up to run.

i found a website with the title Running Fedora Linux on Dell Laptops (http://www.arachnoid.com/linux/dell_laptops_on_fedora.html) and found a solution there to make the sd port work with just two steps:

1. create a file /etc/modprobe.d/cardreader-firewire.conf with the value:

options firewire-ohci quirks=0x10

2. recreate initramfs image

# dracut --force

after reboot, your sd card reader should work.

warning, though. my wifi stopped working after my reboot. i had to update my wifi and reboot again:

# yum update kmod-wl
# reboot


if no kmod-wl update is available, you can try uninstalling and reinstalling kmod-wl and see if that works.
