Public bug reported:
Expecting faster WIFI from the Intel AGN4965 chipset, I installed
linux-backport-modules-2.6.24-23. The wifi interface stopped working after a
suspend/resume cycle. Logs show that the driver failed to reload after resume,
because the module stack now included lbm_iwl_mac80211 which failed to load.
The following messages appeared in /var/log/messages:
