Would you mind trying the kernels here?


These have a later version of the iwl4965 driver.  Do they work more reliably 
for you?

Comment 3 andy prowse 2007-08-06 16:41:59 UTC
I am using the latest linville kernel: kernel-2.6.18-36.el5.jwltest.41.x86_64.rpm
Latest firmware from http://intellinuxwireless.org

I changed modprobe.conf:

alias wmaster0 iwl4965 to alias wlan0 iwl4965

For 2 hours I have been pinging the router under wirless (no eth0 connection)
and have a script to ifup/ifdown wlan0 every 10 seconds.  It has been running
OK.  No WEP.  I do not know the make or router at my location

I do not know if my previous problems are due to:

1. My router at home is a speedstream DSL
2. I was using WEP at home.

I am going to get a wireless router tonight and test with WEP.

Comment 4 Geoff Gustafson 2007-08-06 17:16:07 UTC
If you do narrow this down to interaction with a particular access point, that
would be great information to submit to bughost.org and we can try to get the
upstream Intel team to find that WAP and start testing with it.

You've used other Linux wireless cards with that AP?

I have used RHEL5 with an ipw3945 with WEP OK, also a Linksys WPC54 pcmcia with
ndiswrapper under RHEL 4 and 5.

Comment 6 Geoff Gustafson 2007-08-06 17:58:31 UTC
Actually, if you could please file at bughost.org in any case. That will get it
seen by Intel's upstream developers; they should really know about this issue,
especially what you see in 1.0.0 (rather than 0.0.34, to which they'll probably
say, go upgrade).

They will have better questions to ask you for more information.

Comment 7 John W. Linville 2007-08-08 17:37:06 UTC
Andy, any word on your testing w/ WEP?  Testing here for several hours of 
active file transfers on both X61 and the Santa Rosa SDV has been running w/o

Comment 10 Larry Troan 2007-08-13 18:33:41 UTC
Changing Summary to reflect Fujitsu hardware per John Linville's request.

Comment 11 Larry Troan 2007-08-13 18:34:43 UTC
Setting severity per conversation with Fujitsu-Canada (was low).

Comment 12 Don Zickus 2007-08-15 19:09:58 UTC
in 2.6.18-40.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5

Comment 13 andy prowse 2007-08-16 01:58:51 UTC
Hi Guys,
Tried the new kernel, still panic's the same way

Comment 14 Geoff Gustafson 2007-08-16 14:34:54 UTC
I have a test kernel here that has the latest patches from
intellinuxwireless.org (1.0.0-1), if someone can provide it to Andy:

Comment 15 andy prowse 2007-08-16 15:50:50 UTC
Hey Guys,

Can you make this available on a people page?  I just need the i686 kernel for
now, as that what the install is on the notebook.


Comment 16 Geoff Gustafson 2007-08-16 15:56:59 UTC
D'oh. I'll have to rebuild for i686 then. :)

Comment 17 Geoff Gustafson 2007-08-16 17:34:36 UTC
Okay, I've posted the i686 kernel to that same URL. I'm still dependent on
someone to post the kernel externally or give me permission to do so.

Comment 19 John W. Linville 2007-09-26 13:02:01 UTC
Can we move all new activity to bug 252981 please?
