This evening I upgraded my hp2133 notebook from Ubuntu/Maverick to the new Natty. The upgrade went smoothly but now the system hangs about 2 minutes after Broadcom 4311 802.11a/b/g wifi is enabled.
Here is the bug report: BCM4311 wifi hangs hp2133 notebook after 2 minutes
Some suggestions from IRC are to try the bcmwl-kernel-source or linux-backports-modules-net-natty-generic packages.
