Comment 3 Cristian Aravena Romero 2010-05-16 03:01:18 UTC

See bug #15794

Comment 4 John W. Linville 2010-05-17 20:06:21 UTC

Looks like we are timing-out on an association w/ a BSS with which we are not (any longer?) authenticated?

Comment 5 Cristian Aravena Romero 2010-05-18 20:22:22 UTC

I use WPA for authentication

Comment 6 Johannes Berg 2010-05-19 09:47:41 UTC

Hm. I thought this was fixed by 79733a865c7fd778ce45e3503962b3a875b0a153 but maybe not?

Comment 7 John W. Linville 2010-05-19 12:55:50 UTC

Ah, well -- that commit isn't in 2.6.34-rc7.  Cristian, can you recreate with 2.6.34 (or later)?

Comment 8 John W. Linville 2010-06-03 19:03:19 UTC

Comment 10 John W. Linville 2010-06-07 15:53:15 UTC

I guess 79733a865c didn't fix it afterall, although I agree that it seems like it should have done so...

Johannes, any other ideas?

Comment 11 John W. Linville 2010-08-18 19:53:57 UTC

Johannes, ping?

Comment 12 Johannes Berg 2010-08-18 20:07:56 UTC

Err, sorry, no more ideas really.

Comment 13 John W. Linville 2011-01-18 19:07:18 UTC

Does this issue persist with 2.6.37 or later kernels?

Comment 14 Cristian Aravena Romero 2011-01-18 22:03:42 UTC

Not message in kernel 2.6.37 =)
