With 2.6.35.x, I saw warnings like below in dmesg.

With 2.6.36-rc6, I even had a flood of them. Is it something to worry about? What causes it?

You can see more of these under http://www.virtall.com/files/dmesg-btrfs-flood.txt

I have also had a lot of these with .36. I don't know why. I'm running
on a laptop which has never been shut down with an improper umount as
far as I can remember. Mount options are
"noatime,noacl,compress-force,thread_pool=3D4,nobarrier"
Nothing on .35

Regards,
Sebastian J.

Hi,

that issue is allready reported to this mailinglist and there is a longer
conversation about it.


Cheers,
