Comment 1 Mads Kiilerich 2011-07-29 15:05:03 UTC 
This is really a duplicate of Bug 726701, but abrt wasn't able to parse the lgo message and gave it a non-descriptive title.

abrt-2.0.4-1.fc16.i686
Comment 2 Nikola Pajkovsky 2011-10-05 15:57:30 UTC 
what kind of message isn't abrt able parse?
Comment 3 Mads Kiilerich 2011-10-05 22:37:20 UTC 
I assume the backtrace above demonstrates the problem: abrt didn't know where the backtrace context started and included too many initial lines.

I didn't make it very clear that a part of the problem was that abrt filed this bug was this misleading subject:
[abrt] kernel: RCU dyntick-idle grace-period acceleration is enabled.: TAINTED -----B---W 
(see bug history)

I assume it should have used the WARNING line, which is the first line after "cut here".

The dmesg attachment on bug 726701 shows the full dmesg.
Comment 4 Jiri Moskovcak 2011-12-09 12:54:20 UTC 
ABRT was triggered by the line:

Oops: efitime: can't read time!

which is also an oops and missed the second (more important) oops.

Comment 7 Jiri Moskovcak 2012-02-27 12:49:35 UTC 
This should be fixed in current abrt.
