Some files (2-3) got corrupted in my /home subvolume for no apparent reason. Trying to access the files gives kernel oops. Sometimes it freezes the machine, sometimes I am back to my console without any problems. Then I switched to the latest 3.1rc and freezes were gone (though I still had the kernel oops). (I did not try the repair program fearing that it would do more bad than good. After all, my / subvolume was fine and i still could mount /home) But to tackle the problems with corrupted files I had to create a new subvolume for /home, tranfer the files from the old one (minus the corrupted files) and delete the old subvolume. Though still btrfsck would give me errors trying to access some inode. But I could mount and use all my subvolumes with no problems. Then... I re-created btrfs with the latest btrfs-tools and installed the latest 3.1rc from the very beginning. So far, it is working fine and the situation with disk I/O has greatly improved. I think you may want to try to upgrade to the latest 3.1rc and at the very least you (hopefully) should not be getting hard freezes any more. best ~dima
