RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Paulo Roma Cavalcanti 2012-09-23 14:56:05 UTC
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:
1.
2.
3.
  
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?

kernel used 2.6.32-279.9.1.el6.x86_64

Comment 4 Paulo Roma Cavalcanti 2012-09-29 13:50:50 UTC
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 12:14:31 UTC
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 22:19:08 UTC
There is any workaround until kernel upgrade ...???

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

P.S.
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
