just booted a fresh 3.5 kernel and got the following on login via gdm
on the client computer
didn't see any crashes yet on any other computer but didn't give it
long to try after seeing this
let me know if you need more info
this client is running debian wheezy 64bit

This is a different stack trace than another recent report. Quick
question: have you run 3.4 on this system?

been running it for a while now currently got 3.4.7 and 3.4.6
on the 2 systems that would likely see that bug (since its a gnome app
triggering it)
and they are both stable and show no issues

it looks like you have a patch for this problem in a queue somewhere
(email found on ocfs2-dev:
https://oss.oracle.com/pipermail/ocfs2-devel/2012-August/008677.html )
but its not in 3.6, any reason for the delay?
I've been running that patch on 3.5 for a while now likely since
around the time i found that email
and its been working well

doesn't look to be in 3.7 or 3.8-git
and from what i see on ocfs2-dev there are at least 16 other patches
that are also being ignored?
I'm sure if I'm bothering at this point to maintain my own patchset to
keep ocfs2 from crashing
that there is other folks doing the same

Please resend all OCFS2 patches, cc'ing myself, Mark, Joel and
ocfs2-devel@oss.oracle.com.
I shall then review them, merge them into -mm (and hence linux-next) so
they can get a bit of visibility and testing while the maintainers are
checking them over.
Thanks.

I've just been browsing the ocfs2-dev archives do you want me to pull them
and resend or should i just link to the archive?
keep in mind I'm just a end user not really a dev persay
if you do want me to send the patches however I assume there is a document
i should read first?

Well, someone needs to resend them. If you're prepared to do that then
thanks, and please remember to add your Tested-by where you feel that's
appropriate.

Documentation/SubmittingPatches is good.
These patches should have a From: line at the start of the changelog
indicating the original author. They should have the original author's
Signed-off-by: (if that was in the original patch) and also your
Signed-off-by: as you were on the delivery path. And optionally your
Tested-by, as above.
Be sure to cc everyone (ocfs2-devel, linux-kernel, Mark, Joel, myself
and the original author(s).
Lots of email clients like to mangle patches, including gmail :( Email
the patchset to yourself first and check that what you received still
applies. Try using text/plain attachments if they are being mangled.
