Hello,

I had some problems with my wifi card (Edimax IEEE 802.11n Wireless lan pci card) wich I didn't have under trisquel 6. On both versions it wasn't recognized and I could not use wifi, but under trisquel 7 it continuously covered my terminal with this message :

This made my cpu work at 100% all the time. So, following the advice of magic banana on the french forum, I firts installed linux libre 3.17 from jxself repo and it fixed my cpu problem, but I still had the message. So i tryed to blacklist related processes in /etc/modprobe.d/blacklist.conf :

rt2800pci
rt2800mmio
rt2800lib
rt2x00pci
rt2x00mmio
rt2x00lib

But it didn't work.

After having some boot problems and the return of cpu problems, even with tghe new kernel, I decided to unplug my wifi card and I had no more problems.

I would like to be able to let my wifi card plugged, even if it's not recognized by trisquel to be able to use it with another distro in case of need.
I would also like to know if I can come back to the default kernel without issues.

The lines you added to /etc/modprobe.d/blacklist.conf are like
"blacklist rt2800pci" or just the module names? It needs the
"blacklist" keyword. Your card is handled by 2800pci, the firmware is
loaded by rt2x00lib.

You might need to run update-initramfs if the module is loaded by
initramfs, I don't know if it is.
