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: ==== [EMAIL PROTECTED]:~ $ sudo ifconfig ra0 up [EMAIL PROTECTED]:~ $ sudo ifconfig ra0 down [EMAIL PROTECTED]:~ $ sudo ifup ra0 Internet Systems Consortium DHCP Client V3.0.3 Copyright 2004-2005 Internet Systems Consortium.

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. -- Dapper 5, wireless RT61 problem https://launchpad.net/bugs/34709 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
