> Just happened while writing a huge avi file to my usb3 backup disk:
Same problem here, I try to give the filesystem history:
a) three days ago I format a 219GB partition:
1) latest Linus' git kernel tree;
2) two nested subvolumes;
3) options:
defaults,noatime,nobarrier,ssd,noacl,compress,subvol=root,autodefrag
b) I copy ~90GB of data;
c) I mount same as above, without compress;
d) I copy other data, to ~140GB;
e) run balance, after a while I had to poweroff;
f) two days ago, I boot and it finishes the balance;
g) I put in cron a snapshot every hour;
h) today (after a lot of clean resume/suspend in RAM) I run VirtualBox
and start an Ubuntu 12.04 install in Guest;
i) near the end of installation VirtualBox get stuck (but everything
else works) and kernel complain:
