[Bug 34709] Dapper final wireless RT61 problem

[Paul McGarry]

I seem to be experiencing this problem on Dapper final.
I have a D-link DWL-G510 Revision C1 wireless desktop adapter.

iwconfig uses all of CPU and top shows it is 100% sys.

Trying to do anything with the process (attach gdb, killing it, strace)
doesn't work. The gdb/kill/strace just sits there doing nothing.

The odd thing is that I can get the connection to work. It seems that if I do:

If I try it without doing the ifconfig up/down beforehand then it just hangs

and that's it.

I have no idea why this would make a difference but am happy to
investigate further if given a bit of direction. I have had this card
for at least 6 months and after failing to get it to work on Breezy this
is the first time I have tried to get it going on Dapper.

The workaround isn't much use because I need the connection to start up
automatically and adding

auto ra0

to /etc/network/interfaces just causes the server to hang with iwconfig
at 100% cpu on start up and seems to block a lot of other stuff starting
properly (X for example complains that it failed to load the NVidia
kernel module) and the server startup process eventualy stops dead when
trying to start the Firestarter firewall.
