I think this will be fixed by the local_bh_disable patch I posted
recently.

I think something similar to this was reported by Thomas Gleixner on a
NUMA machine. The subject was "[BUG] Lockdep recursive locking in
kmem_cache_free" , there was a patch provided by Ravikiran G Thirumalai
that remove the warnings.

I don't think I've seen this one reported yet.
This kernel was a 2.6.18rc3-gitSomething, but I don't think
anything has changed recently that would explain this?

Subject: [Bug 201726] New: massive kernel spewage with DWARF2 unwinder errors
Date: Tue, 8 Aug 2006 11:36:34 -0400
Message-ID: <bug-201726-176318@bugzilla.redhat.com>
Please do not reply directly to this email. All additional
comments should be made in the comments box of this bug report.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201726
Summary: massive kernel spewage with DWARF2 unwinder errors
Product: Fedora Core
Version: fc6test2
Platform: x86_64
OS/Version: Linux
Status: NEW
Severity: high
Priority: normal
Component: kernel
AssignedTo: kernel-maint@redhat.com
ReportedBy: netllama@gmail.com
QAContact: bbrock@redhat.com
CC: wtogami@redhat.com
Description of problem:
Version-Release number of selected component (if applicable):
2.6.17-1.2517.fc6 and 2.6.17-1.2530.fc6
How reproducible:
Steps to Reproduce:
1. Boot, and the fireworks begin early on at "checking if image is initramfs..."
2. Even after booting, there's a ton more spewage, seemingly at random when
doing things as simple as ssh/scp, and also when running the attached sysreport.
Actual results:
#######
checking if image is initramfs...
=============================================
[ INFO: possible recursive locking detected ]
