Description Jesse Keating 2008-02-17 16:10:04 UTC
I'm running kernel-2.6.25-0.40.rc1.git2.fc9 on an x86_64 laptop with an iwl4965
wireless card.  Prior to 2.6.24/25 my wireless would work perfectly after
suspend.  It would take a few moments and then scan (via NetworkManager) for
access points.  When I started using 2.6.24 I had to resort to modprobe -r /
modprobe the 4965 module to get it to scan again.  Today I started using the
2.6.25 builds and now the probe dance doesn't even work.  I get messages that
the device doesn't support scanning (iwlist wlan0 scan).  A reboot was necessary
to get wireless functionality back.

I am currently using hw scanning (no module options), but I'm about to try sw
scanning.  Will report findings.

Adding to the Beta list as it would be a shame to regress this for F9 Beta.

Seems with sw scanning I can do the modprobe -r / modprobe trick to get wireless
again, but it continues to not just work after suspend/resume.

Comment 4 John W. Linville 2008-03-04 19:52:32 UTC
I can not recreate this on my 4965-equipped t61 with 2.6.25-0.87.rc3.git4.fc9 
running on an F8 userland (augmented with mkinitrd and related components from 
rawhide).  Are you still seeing the issue?

Comment 5 Jesse Keating 2008-03-04 20:03:43 UTC
I'm now fully on rawhide, and may or may not have suspend issues (:  I'll let
you know next time I have a successful suspend/resume.

Comment 6 Jesse Keating 2008-03-05 19:37:41 UTC
Seems fine in rawhide now.
