Description Stuart Campbell 2005-03-01 16:36:04 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Description of problem:
If I enable the wireless interface from the slide switch on the laptop the computer freezes (except for the caps lock light flashes on/off).

This worked perfectly under RHEL 4 Beta2.

This happens with Toshiba Tecra M1 and M2 models.

Comment 2 Stuart Campbell 2005-03-24 16:04:37 UTC

This problem seems to be solved in the latest rawhide kernel.

Comment 3 John W. Linville 2005-04-25 19:28:26 UTC

FWIW, the ipw2200 driver is the same in rawhide, fc3, and rhel4... 
 
The kernels here have an updated ipw2200 driver: 
 
   http://people.redhat.com/linville/kernels/rhel4/ 
 
This is the same driver that is schedule for U1.  Could you give it a try and 
report back the results?  Thanks!

Comment 4 Stuart Campbell 2005-05-03 07:21:37 UTC

This seems to work perfectly.  
Thank you
