[Bug 48087] Re: RT61 driver hangs net, if interface accessed while down

[Warbo]

I found the same issue as Aldous D. Peñaranda with a PCI card. The system would come up with GDM, but not log in (just stop loading before the desktop comes up, mouse pointer still movable).
Switching to a console and running top showed "iwlist" as taking over 90% CPU power. (Pressing ctrl-alt-f8 to see the boot messages had the last as starting DHCP server, although I don't know whether was just because it was the last task)
iwlist was not killable since trying to use sudo would hang the terminal, so I had to boot into recovery mode and move iwlist out of $PATH. After doing that Ubuntu booted fine (I have reinstalled since, so I may not be able to reproduce it)
