PS: I upgraded several other systems (they are using dm with LUKS too but are all ext4, no XFS like this VM) to linux-4.1.9, too and they all freezed while running (booting was never a problem like with the system using XFS). Some of them were running for hours until they freezed, some freezed just seconds after start up finished. Because I haven't seen the BUG_ON on any of these systems before with linux-4.1.8 I am not sure if this is the same problem (and the system with XFS from where I showed you the trace seems to boot fine with linux-4.1.9 but now freezes, too). Any idea how to debug the freeze? PS2: On Google I found http://oss.sgi.com/pipermail/xfs/2014-November/039105.html -- that's why I am mentioning that I am using XFS (and except to the file system the VM is identical with the other VMs which didn't show any problems until linux-4.1.9). I cannot find the patch from http://oss.sgi.com/pipermail/xfs/2014-November/039149.html in the kernel mainline. Is it worth to check that direction, too or doesn't the trace indicate any relationship?
