I am having trouble getting my laptop (Thinkpad T41, FC8 with latest updates,
atheros wifi) working with suspend to ram. The ath5k driver works with
NetworkManager until I try to resume from suspend.
In all the examples below, the failure mode is always the same: dmesg produces
lots
of
WEP decrypt failed (ICV)
messages, and NetworkManager shows two green lights but spins forever.
Eventually
it gives up and starts asking for a new WEP key.
What does not work:
a) suspend, resume, restrart NetworkManager
What does not work:
b) unload ath5k mac80211 cfg80211 modules (via
/etc/pm/config.d/unload_modules),
suspend, resume, modprobe ath5k, service NetworkManager restart
What works sometimes:
c) unload ath5k mac80211 cfg80211 modules (via
/etc/pm/config.d/unload_modules),
suspend, resume, modprobe ath5k, WAIT 5 MINUTES, service NetworkManager
restart
What works always:
d) use system-config-network instead of NetworkManager,
unload ath5k mac80211 cfg80211 modules (via /etc/pm/config.d/unload_modules),
suspend, resume (now network comes back automatically).
Another thing which does not ever work:
e) use system-config-network instead of NetworkManager, but do not unload the
modules at suspend time.
Is there any way to track this down? I would file this in bugzilla if I knew
which
component to blame.
Best,
Alex
