Description Paulo Roma Cavalcanti 2012-09-23 10:56:05 EDT
Description of problem:

If I use any kernel of the 2.6.32-279 series
my laptop (Dell Vostro 1400) freezes after sometime,
and a blue light starts to blink on the keyboard.
I have to shut down by holding the power button... 

My kernel is tainted because I use the proprietary nvidia
driver, but the culprit is the iwl3945 module. 

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

Kernel 2.6.32-279.5.2.el6.x86_64 was my last unsuccessful attempt.

How reproducible:

Just boot in any recent rhel6 kernel and wait some time ...

Steps to Reproduce:
Actual results:

Expected results:

Kernel should work as before the 279 series.

Additional info:

Kernel 2.6.32-220.23.1.el6.x86_64 works just fine.

Perhaps you can tell us what makes you think that iwl3945 is the problem?

The network works for a few minutes
and then the connection is lost. 
If I leave the system running this way, it just freezes.

This has been happening since the first 279 kernel,
with either the stock RedHat kernel or Centos. I tried
everything I could. It only works with kernel-2.6.32-220.23.1
or below.

I run rhel6 on several other desktop/notebooks with
no problem at all, but this is the only notebook I have 
with this wireless hardware from Dell...
Comment 5 Stanislaw Gruszka 2012-10-03 08:14:31 EDT
This is memory leak which will be fixed on RHEL6.4 . If you need that fix in RHEL6.3 you have to contact official RH support.

Comment 6 Cristian Gheorghe Florescu 2013-03-05 17:19:08 EST
There is any workaround until kernel upgrade ...???

I've the same issue on HP 6710b ...

I almost proceed to change my hdd until I identified that is a bug.
SATA hdd freeze and kernel coud not manage current tasks in terms of IO.

Thank you
