so i'm curious if anyone else noticed problems right after moving to
f7.
Mine worked with FC4 but not FC5 and FC6. F7 works. It is all a
crap shoot. Go back to FC6 or wait for F8.
The problem is a little more complex than that...
There is an issue with the Broadcom chipsets (bcm4306 in particular). I
will explain it as well as my information will allow.
Some versions of the bcm4306 chipset work with the version 3 firmware, but
do not have enough memory to load the version 4 firmware. The old bcm43xx
driver uses the version 3 firmware. The new driver (bcm43xx_mac80211?)
only works with the version 4 firmware. So older chipsets do not work
with the new driver. And here is the fun part... Both chipsets have the
same pci id, so it is hard to tell which of the two chipsets you really
have. (Since the kernel module uses the pci id to figure which one to
load, it has to pick one. It does not look at chip revision information.
You have to hack the blacklist and pci info files.)
Fun.
I believe this is a problem that was found after the module was written.
I am not certain if there is a fix possible for this without removing and
replacing hardware. (Which is hard if you have a laptop with the older
chipset, like I do...)
Hope that helps...
