Bug 98239 – ipw2100 incompatible with gentoo-sources-2.6.12-r4?

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Frank Lomax 2005-07-07 10:02:01 UTC]

I just updated my laptop to gentoo-source-2.6.12-r4 from 2.6.11-r11 and now my
ipw2100 wireless card seems to be broken.  Whenever I update my kernel I always
have to re-emerge ipw2100 to get it to build against the new kernel.  Did that
again this time and all seems to go okay, except that after rebooting, the
kernel module gets loaded fine but I can never get a DHCP lease.  It's not a
local problem because rebooting back to 2.6.11-r11 works just fine, as before.

Reproducible: Always
Steps to Reproduce:
1.emerge --update gentoo-sources
2.reboot
3.emerge ipw2100
4.reboot to 2.6.12-r4

Actual Results:  
System hangs attempting to get DHCP lease, then gives up with no wireless
connection.

Expected Results:  
Same as with 2.6.11-r11, the system should get DHCP.

Please provide the relevant output of `dmesg` and the output of `emerge --info`.
You also failed to tell us which version of the ipw2100 you are using...

ipw2100 version 1.1.0

emerge --info and dmesg output to be attached

Reopening with requested information

[Comment 6 Henrik Brix Andersen 2005-07-08 07:38:38 UTC]

The dmesg output doesn't show any errors - it does however show that you are
using WEP. Please see if you can reproduce the problem with WEP disabled.

[Comment 7 Frank Lomax 2005-07-08 08:19:31 UTC]

Disabling WEP won't work because the access point is definitely configured for
WEP.  I tried it for grins, but as expected, it refused to associate.

[Comment 8 Frank Lomax 2005-07-08 08:20:35 UTC]

BTW, I don't have control over the access point to disable WEP there.  I'll see
if I can dig up a test access point though.

[Comment 9 Henrik Brix Andersen 2005-07-08 09:17:25 UTC]

Please report back when you've tested against a non-WEP AP.

[Comment 10 Henrik Brix Andersen 2005-07-08 12:38:04 UTC]

Reporter, please see if ipw2100-1.1.1_pre11, which can be found in my overlay,
fixes this issue: http://dev.gentoo.org/~brix/files/overlay/

[Comment 11 Henrik Brix Andersen 2005-07-08 13:32:23 UTC]

This might be a similar race condition as the one reported upstream at
http://www.bughost.org/bugzilla/show_bug.cgi?id=715

Please try the patch from the above bug report, and report if it solves your
problem.

Unfortunately, I can not reproduce it here...
