From the attached screenshot it rather looks that it is VFS that died (task 6 is init:vfs). Run on Qemu with KVM on amd64 build (default configuration except bigger screen and ext4fs as root FS).

Update: tested on latest mainline (1636), but the same problem occurs in 1595 as well (since that revision it is possible to use Ext4 as root FS).
