Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-btrfs-owner@vger.kernel.org List-ID: Howdy, So I run several gentoo systems and I upgraded two of them to kernel 3.17.0 One using BTRFS for root. One using ext3 for root (via the ext4 driver) _Both_ systems exhibited strange behavior (long pauses and then hangs requiring hard-power) within several hours. Both then had random filesystem damage. On the BTRFS system much of my browser settings for firefox were trashed, particularly the cookies and saved conifigurations for add-ons (like which sites had scripts enabled/disabled in no-script) etc. On the ext3/4 system there were several corruptions including a pipe/special file with a large non-zero size that required I do a "fsck -fyD /dev/sda3" to repair. (one comment from fsck was that the pipe/special file "looked like a directory" or some such) So I can say that corruption is taking place, but I suspect it is _not_ happening in the BTRFS specific code. (ASIDE: both systems are older amd64 using built-in radeon display hardware.)
