Description Kevin Fenzi 2009-04-09 02:14:18 UTC
kernel 2.6.29.1-37.rc1 boots and runs normally here. 

kernel-2.6.29.1-46.fc11.x86_64
kernel-2.6.29.1-52.fc11.x86_64
kernel-2.6.29.1-54.fc11.x86_64

All fail in this same way: 

Boot up is normal. X comes up fine. I login. 
Everything starts loading. 
NetworkManager loads and starts trying to connect to my wireless network. 
Machine hard locks. No answer from any keys. ;( 

I do have an intel 3945 wireless here, so I wonder if: 

* Thu Apr 02 2009 John W. Linville <linville>
- iwl3945: rely on priv->lock to protect priv access

* Thu Apr 02 2009 John W. Linville <linville>
- back-port iwlwifi rfkill while device down patches

Could be causing it? 

Happy to provide more info or try any tests.

Comment 1 John W. Linville 2009-04-09 15:10:14 UTC
Just to be sure, could you try each of the following kernels?

   http://koji.fedoraproject.org/koji/buildinfo?buildID=96417

   http://koji.fedoraproject.org/koji/buildinfo?buildID=96424

Do both of them fail similarly to -46.fc11 and after?  Or perhaps just the second one?

Comment 2 Kevin Fenzi 2009-04-09 15:17:54 UTC
The first of those seems to be a canceled task?

I can try the second one later this morning.

Comment 3 John W. Linville 2009-04-09 15:24:17 UTC
Ah yes, sorry...I forgot that I cancelled that build when I added the priv->lock patch...

Comment 4 Kevin Fenzi 2009-04-09 17:45:23 UTC
ok, the kernel-2.6.29.1-42.rc1.fc11.x86_64 kernel also locks up here. 

It locked up in a slightly different way. The others totally locked, this one I could still watch my gkrellm update and see that something was taking 100% cpu, but couldn't use the mouse/keyboard at all. 

Happy to try further testing.

Comment 5 John W. Linville 2009-04-09 18:07:28 UTC
Cool, thanks...first let's try dropping both of those patches:

Please give those kernels a try when the build completes...thanks!

2.6.29.1-64.bz495003.1.fc11.x86_64 boots and runs normally. 
wireless comes up, no lockup.

Comment 8 John W. Linville 2009-04-13 14:16:35 UTC
Looks like lots of people are hitting this on iwl3945.  Not sure if that is
what you have, but on a hunch I did a version that only removes the iwl3945
priv->lock patch.  Would you mind trying this version (when the build
completes)?

Comment 10 Kevin Fenzi 2009-04-13 16:26:13 UTC
The kernel from comment #8 works fine here so far. ;)

Comment 11 John W. Linville 2009-04-13 17:13:31 UTC
Cool, thanks!

Comment 12 Nigel Jones 2009-04-13 20:45:46 UTC
Special kernel seems to work fine here too after reverting to the "bad" AP configuration... great.

Comment 13 Nigel Jones 2009-04-16 05:55:52 UTC
Appeared to get hang with -70 kernel. Didn't debug but downloaded -85 from koji which works fine with the "bad" AP.

Possibly unrelated, but latest kernel seems good for this problem. Thx.
