Description Andrew Overholt 2008-06-26 10:20:17 EDT
Description of problem:
I'm running x86_64 Fedora 9 on a Thinkpad x61.  I've hibernated a few times
since getting this laptop last week, and never really noticed this before, but
this morning when I turned it back on, it can no longer connect to the wireless
network.

Version-Release number of selected component (if applicable):
kernel-2.6.25.6-55.fc9.x86_64

How reproducible:
Not sure

Steps to Reproduce:
1. hibernate
2. wake up (connected to dock ... don't know if that matters)
3. modprobe -r iwl4965; modprobe iwl4965
  
Actual results:
No wireless device.  dmesg contains:

iwl4965: Tx 0 queue init failed
iwl4965: Unable to init nic

Expected results:
Wireless device works.

I don't know if this is related, but I just suspended (to memory) my laptop and
opened it while in the dock and it hung while getting a wireless network
connection.  I hard-restarted it and the same thing happened twice more.  I
rebooted into 2.6.25.4-30.fc9.x86_64 and it seems to be working fine.
Comment 2 John W. Linville 2008-06-26 11:28:58 EDT
Many have reported such hangs with -55.fc9.  Please try -57.fc9 or later:

Are you still experiencing this issue with current F9 kernels (e.g. -97 or 
later)?
Comment 4 Andrew Overholt 2008-07-31 12:04:03 EDT
I can't seem to hibernate with -97:  bug #457424.
Comment 5 John W. Linville 2008-12-11 13:52:38 EST
Are you able to recreate this now?
Comment 6 Andrew Overholt 2008-12-11 14:32:24 EST
Looks like it works with 2.6.27.5-117.fc10.x86_64.
