Does this still occur for you? If so, have you tested it in edgy? Upstream noted this was almost 100% likely to be a bcm43xx driver issue. When I tested it against my bcm43xx in edgy, the problem no longer existed.
** Summary changed: - system sluggish when wireless dirver unloaded + [dapper] system sluggish when NM unloaded with bcm43xx driver -- [dapper] system sluggish when NM unloaded with bcm43xx driver https://launchpad.net/bugs/38659 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
