comment:
:New Fedora 15 (gnome 3)
:
:I am downloading backups with rsync over ssh. (rsync -avx root@<source> ...)
:My internet connection is: Notebook via WIFI to router, then via cable modem.
:I go away from my notebook and do something else, because rsync will take some time.
:As I come back, gnome 3 is locked and I have to type in my password.
:As gnome is unlocked, I get a dialogue, telling me to verify my WIFI passphrase. I click ok, nothing happens.
:The LED light on my mashine for WIFI is off.
:At this point, I notice that gnome reports this kernel error.
:I can't get WIFI back to work and do a restart.
:I can reproduce this error anytime.
