(sorry, my responses are a bit delayed, I am on the road, so not a lot
of time for testing)

I just see these lines, which I figured are normal:

Apr 20 07:23:08 happy kernel: b43 ssb0:0: firmware: requesting b43/ucode13.fw
Apr 20 07:23:08 happy kernel: b43 ssb0:0: firmware: requesting b43/b0g0initvals13.fw
Apr 20 07:23:09 happy kernel: b43-phy0: Loading firmware version 410.2160 (2007-05-26 15:32:10)
Apr 20 07:23:09 happy kernel: b43-pci-bridge 0000:02:00.0: PCI: Disallowing DAC for device
Apr 20 07:23:09 happy kernel: b43-phy0: DMA mask fallback from 64-bit to 32-bit
Apr 20 07:23:09 happy kernel: ADDRCONF(NETDEV_UP): wlan0: link is not ready

And then it freezes.

I have also tried disabling the radio using the switch, and then there
is no freeze. When I enable the radio back, it freezes again.
