Hi, recently I noticed one of my Win7 VM is hanging after a few minutes of use and I saw the following output on the journal.

Code: Select all

When this happened, it froze the particular window that I'm working on, i.e. moving a file in Explorer and it goes white, or saving a file in an application and it went white as well. Nothing unusual on VBox's log. This VM reside on Sandisk Ultra II.

I have another Win7 VM which I use more frequently and I don't get this problem, though the images are on a diff SSD, Samsung 850 EVO. I'm running VBox 5.1.2 on Arch (Linux xxx 4.6.4-1-ARCH #1 SMP PREEMPT Mon Jul 11 19:12:32 CEST 2016 x86_64 GNU/Linux). Both SSD is on a btrfs partition on top of lvm on top of dm-crypt. If I recall correctly, it last works fine on 5.1.0 or 5.1.1 couple of weeks before this. I did a scrub and found no error.

Is this a known bug with VBox or could it be issue with btrfs or my particular SSD.
