WARNING: at /build/buildd/linux-2.6.32/net/wireless/core.c:614 wdev_cleanup_work+0xe9/0x110 [cfg80211]()

Wireless stops working every few minutes. Using a 32 kernel I get a report about a kernel problem, using 33 I get the same problem though less frequently and no report about a kernel problem.

Network-manager is reporting to work normally, but I can't access the net.
