Red Hat Bugzilla – Bug 451723
kernel 126.96.36.199-55.fc9.i686, driver iwl4965 freezes system
Last modified: 2009-02-14 15:36:55 EST
Description of problem:
On a Toshiba Satellite A200-237, using the iwl4965 wireless driver that comes
with the 188.8.131.52-55.fc9.i686 kernel freezes the system.
Version-Release number of selected component (if applicable):
kernel 184.108.40.206-55.fc9.i686 as available from the Fedora updates repository.
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.
No syslog messages are given.
Wireless works with kernel 220.127.116.11-30.fc9.i686.
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?
I'll check when 57 or up becomes available. It is not on updates/-testing yet.
Myself and two other co-workers with T61p laptops have this same freeze/lockup
problem that started with 18.104.22.168-55 problem. Bug 451395 is likely a dup of
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.
I also can confirm this. Reverted to previous kernel. Laptop is T61p.
I can confirm this problem on X86_64 with KDE.
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.
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.
I can confirm that it occurs on WEP-40/128 HEX on 802.11g.
I am having the same problem on 22.214.171.124-55.fc9.x86_64 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.
This bug seems to be the same as https://bugzilla.redhat.com/show_bug.cgi?id=451510
