I have some kind of corruption in my btrfs file system that causes kernel
segmentation faults when I try to delete files in my browser cache. Let me
know if you are interested in having any additional information besides what
is below. Thanks.

2.6.38 is quite old from btrfs perspective and it's highly possible that
the bug you've hit is already fixed. Try newer (like 3.1) kernel and if
you still hit some sort of crash, please send the report.

btw such output is printed to every console when the crash occurs, but
lacks important information like stacktrace and names of functions.
without that it's very hard to get a clue what happened.

As for stacktrace and line length, I personally want to see the lines
not wrapped at 80 (except the eg. byte dump of instructions), it helps
readability.

Okay, I installed 3.1.1 and continue to oops when trying to delete a
directory. Please let me know if you would like any additional
information. I'm going to rebuild from a backup later today.
Cheers,Tim

Do you have more detailed stacktraces from the crash?

If you tell me the best way to generate them for you, I will do that.
It doesn't seem that anything is printed to /var/log/messages, and my
machine locks up pretty soon after the segfault, so I haven't been
able to get a detailed stack trace.

Okay, I got it. Dmesg had what I think you need. Some relavent
commands then the trace follow. I was trying to delete my Chrome
cache, because I determined that this part of the file system was
possibly causing my problems. I've heard of others having issues with
Chrome and btrfs. Not sure if this is related. If you figure out what
is going on, I would be interested to hear back. Cheers.

Hi,
I've seen that you have updated to v3.1, but I'm afraid that is not enough...
Apparently the latest code can provide us more debug info(Not just a NULL pointer).
Could you please update to the latest code and see what is going on?
Here it is:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
thanks,
liubo

Okay, I built the version you sent me. I am guessing that this has the
newest btrfs code in it even though it is labeled 3.1.0? Is that
because it has not been merged? Relevant commands and a stack trace
below. Still says something about a null pointer.

To: Liu Bo; +Cc: dave, linux-btrfs

Thanks,
Tim
