Are you only experiencing this issue w/ a 2.6.34 kernel?  Or also
with Fedora-provided kernels?  If the latter, please be sure to open
a bug at bugzilla.redhat.com and Cc: linville@redhat.com when you do.

This looks like the firmware died.  Since this is iwl3945, you might
try a patch like Reinette suggests here:

https://bugzilla.redhat.com/show_bug.cgi?id=589777#c5

Does that enable the device to recover?
