Bug Description
Binary package hint: bcm43xx-fwcutter
Im using a HP pavillion zv5383EA, AMD64 laptop. It has a broadcom wireless chipset. It worked under Breezy (after a fasion) using ndiswrapper and wpa_supplicant. In Dapper, it has never worked. There seems to be support for the bcm43xx, and involved in that is the downloading of microcode via the bcm43xx-fwcutter script.
I can use iwconfig to list wireless device at eth1, however, executing 'ifconfig eth1 up' causes a total hardware lockup - every time. If the microcode isnt applicable to my card, surely it shouldnt have been 'loaded'? and if it is the right code, why the hard lockup?
Ive been hoping this would go away with the 150+ daily updates but it hasnt yet, including a kernel update (in windows - wireless! so cant dig out kernel image #).
If the fwcutter is working for other people, maybe I need to get ndiswrapper out again and try my luck, but I cant help think it should detect incompatible cards and warn somehow.
How does ifconfig cause a hardware lock anyway!
i can't reproduce this under 686 kernel
maybe a 64bit problem
or a driver problem
