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 David Jaša 2012-03-31 10:40:40 UTC
Description of problem:
suggest what to blacklist to reproduce behaviour of tainted kernel on clean debuggable kernel

Version-Release number of selected component (if applicable):
abrt-2.0.8-4.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. an oops or tainted kernel occurs
2.
3.
  
Actual results:
abrt only says that the kernel is tainted:
not-reportable: A kernel problem occurred, but your kernel has beentainted (flags:G        W  ). Kernel maintainers are unable todiagnose tainted reports.

Expected results:
in addition to above line in Details of the crash, add another line like this:
kernel-tainted-by: <list_of_modules_that_taint_the_kernel>

Comment 1 Jiri Moskovcak 2012-06-12 14:19:06 UTC
Is it even possible to find out this information?

Comment 2 David Jaša 2012-06-13 14:38:36 UTC
I think that kernel should log waht tainted it.

BTW after I reported this bug, I learned why the kernel got tainted in my case - it got tainted by first warning, not by some module. The abrt's dedupe mechanism then merged three duplicate warnings to the latest one and then discarded everything (IIRC I reported this in a separate bug).

- yes, this is a known bug and I think it has already been fixed (at least in upstream)

it's fixed by commit

    oops: don't create oops dir in reverse
    
    when kernel starts printing oops, only very first one is not tainted.
    If we start in reverse, it will firstly create direcotry with tainted oops
    and others will be deleted as dup of first one (if there are same), thus
    we loose NOT tainted oops.

but not yet released

Comment 5 RHEL Program Management 2012-07-10 06:45:46 UTC
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 6 RHEL Program Management 2012-07-10 23:02:59 UTC
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Comment 7 Denys Vlasenko 2012-08-03 14:09:02 UTC
Yes, it is fixed in rhel6 git branch too:

Comment 13 Jiri Moskovcak 2013-01-24 14:31:51 UTC
Cause
   When a multiple kernel oops happens in a short period of time ABRT only the first one is relevant, because the later oopses might be just consequences of the first problem. ABRT was wrongly sorting the processed oopses, so it saved the last oops instead of the first one.
Consequence
   The most important first oops never got into problem report.
Fix
   Fixed the processing order.
Result
   In case of processing more oops at the same time the first one is correctly saved
