It's not clear that it's the kernel who is reponsible of this. Shouldnt this be
reported to networkmanager developers first...?

Comment 3 john stultz 2005-10-04 14:00:28 UTC

Probably true. However since something in the kernel (If I go back to 2.6.13
NetworkManager works fine) and triggers the issue I figured I'd file a kernel
bug just in case.

Comment 4 Robert Love 2005-10-11 11:22:09 UTC

As a NetworkManager and kernel developer, I can squarely place the blame: On iwlib.

iwlib 28pre10 (the latest) should fix this problem.

Comment 5 Robert Love 2005-10-11 11:23:01 UTC

Closing bug as not kernel.  Feel free to reopen if iwlibs does not cut it.
