Description Ronny Fischer 2008-07-17 11:23:16 UTC

Description of problem:

after updating Fedora 9 to kernel 2.6.25.10-86 the bootprocess comes with a 
kerneloops warning and login isn't possible. I entered username and password, 
but no login happened (meanwhile I was taking a shower!)

Version-Release number of selected component (if applicable):

fedora 9 64 Bit, Kernel 2.6.25.10-86
 
How reproducible:

always

Steps to Reproduce:
1. upgraded to the latest kernel
2.
3.
  
Actual results:

login screen appears with delay, no login possible

Expected results:

the opposite of the actual results

Additional info:

system hardware is an actual Core2Duo with Intel P35 chipset, the automatic 
kerneloops report has been send

Update:

Same thing happens with the new 2.6.25.11 kernel. Also this kerneloops has been 
send. Additional to that is that the keyboard does not work any more with this 
new kernel, with 2.6.25.10 I could enter my password, now there isn't any 
activity with that.

I also would like to know if anyone deals with this task, there's no response 
by now.

Furthermore I like to mention that the kernel 2.6.25.9 works fine. I'm 
wondering why a kernel update should make the login unimpossible.

Thanx in advance

Another update:

I tracked the error down to the wpa_supplicant application. At my system it is 
used with an Atheros card and the madwifi driver.

Following output is generated when wpa_supplicant is started:

service wpa_supplicant start
wpa_supplicant wird gestartet: /etc/wpa_supplicant/wpa_supplicant.conf, -iath0, 
-Dwext                                                     [  OK  ]

I'm not sure but it seems that there is a problem with SMP threading.

Thanx

I think the problem is the madwifi driver...
