Description Bernie Innocenti 2009-03-31 11:13:13 UTC

The card occasionally hangs and then disconnects from the AP.  The only way to recover from this is "rmmod iwlagn; modprobe iwlagn".

The bug *seems* to trigger much more frequently while transferring large amounts of data in both directions, but I've seen it a couple of times when the wifi link was not particularly loaded.


Version-Release number of selected component (if applicable):
kernel-2.6.29-16.fc11.x86_64 
kernel-firmware-2.6.29-16.fc11.noarch

How reproducible:
Every few hours, more often under high load.

Steps to Reproduce:
1. Connect to an AP.
2. Run a couple of large rsync jobs in both directions
3. Wait...
  
Actual results:
Card hangs

Expected results:
Card should not hang, please

Comment 1 Bernie Innocenti 2009-04-08 01:05:11 UTC

Confirmed with 2.6.29.1-37.rc1.fc11.x86_64.  Occurs quite frequently when transferring large files with rsync.  The only way to unstuck the driver is rmmod + modprobe.
