Since I heard absolutely nothing on my last but and corruption report, I'm
not sure if they are useful or wanted (please let me know).
The last thing I've seen with 3.4.4 is this:

I managed to capture the entire output using netconsole by modifying
the kernel to not output the list of modules.

I though about th

On June 22th 2012, David Sterba posted a patch to change the ioctls
for the commands to get/reset device stats in the kernel.
Intentionally, this was not backward compatible since the goal was to
get rid of one of the two ioctls. And it was early enough before any
Linux release included the device

Stephan,
Thank you for the analysis. Yes, I fully switched the dmsetup to
"error". Below are my kernel logs, in case you still need them.
Thanks,

Hi there,
A couple days ago, I have converted my Ubuntu Precise machine from ext4
to BTRFS using btrfs-convert.
I currently use kernel:

I now repeated this on 3.4.4. Merely running a "btrfs scrub start /"
causes this after a couple of minutes of running. This time I didn't
run "btrfs scrub status /" in a loop, so that's

Hi Josef,
tested with your "master" branch, commit
157331741ba010ffcb2212b88342fb21ae140636.
fio compiled from tag fio-2.0.8 (commit
cf9a74c8bd63d9db5256f1362885c740e11a1fe5).
Result: some kernel warnings about hung tasks, fio segfault and
mismatch errors. Below are some outputs... I will try some
33 matches
