hi there, here are two new tasks blocking for more than 120 seconds. but this time the task "kjournald2" followed dy "rsync" are affected. this happens when i tried to copy from one ext4 volume to an other with rsync. So its not samba - specific as i assumed at first let me say it seems to be a problem with ext4.
Since i converted two of my volumes from ext3 to ext4 in the last week i got this problems. So i have to go back to ext3 to avoid loosing of data.
