Description of problem:

On a Toshiba Satellite A200-237, using the iwl4965 wireless driver that comes
with the kernel freezes the system.

Version-Release number of selected component (if applicable):

kernel as available from the Fedora updates repository.

How reproducible:


Steps to Reproduce:
1. Boot the notebook.
2. Activate the wireless.
3. While the NetworkManager tries to setup the connection, the system freezes.
The CapsLock led flashes.

Additional info:

No syslog messages are given.

Wireless works with kernel
The wireless connection is with an AP that is WEP protected. The AP codes are
available in the keyring.

I believe this is fixed in -57 and up?
Comment 2 Johan Vromans 2008-06-17 09:12:55 EDT
I'll check when 57 or up becomes available. It is not on updates/-testing yet.
Comment 3 Dax Kelson 2008-06-17 19:41:42 EDT
Myself and two other co-workers with T61p laptops have this same freeze/lockup
problem that started with problem. Bug 451395 is likely a dup of
this bug.
Comment 4 Trond Danielsen 2008-06-18 01:47:42 EDT
I can confirm this bug on x86_64. Laptop is T61p with Nvidia gfx (xorg drv).
Kernel panic occur just after I log into gnome (nm-applet starts?). If I boot
with the hw rf killswitch turned of, the problem is no longer present.
Comment 5 Tore H. Larsen 2008-06-18 19:15:06 EDT
I also can confirm this. Reverted to previous kernel. Laptop is T61p.
Comment 6 Julien Dambron 2008-06-19 01:24:14 EDT
I can confirm this problem on X86_64 with KDE.
Comment 7 Mike Hanby 2008-06-20 16:13:09 EDT
I can confirm this with i686 version running on a Dell XPS m1330 notebook with
the Intel 802.11n wifi card. Reverting to previous kernel I can successfully
login to the gnome desktop.
Comment 8 Adam D. Ligas 2008-06-21 02:13:40 EDT
Confirmed on T61 (iwl4965) running X86_64.  The machine freezes when the second
"dot" in NetworkManager lights up.  Caps lock flashes, machine totally frozen. 
Reverting to previous kernel appears to work around the issue.

Bug does *NOT* occur at my home where I run Wireless-G with WPA2 security.

Bug *DOES* occur at my girlfriend's house where she runs Wireless-B with WEP-128.
Comment 9 Tore H. Larsen 2008-06-21 04:08:01 EDT
I can confirm that it occurs on WEP-40/128 HEX on 802.11g.
Comment 10 Ian 2008-06-22 15:17:31 EDT
I am having the same problem on with an Intel 4965 AGN
wifi card. I can get my computer to boot by eater using an older kernel version
or by booting with wifi off, but if I turn it on it will freeze.
Comment 11 Ian 2008-06-22 17:18:30 EDT
This bug seems to be the same as https://bugzilla.redhat.com/show_bug.cgi?id=451510
