LOR on 11.0-ALPHA5 amd64

Hi,

I got this LOR today on a 11.0-ALPHA5 amd64 (FTP installation)
instance running in Virtualbox 5.0.24 r108355 with Windows 10 as a
host:

1st ufs (ufs) _at_ /usr/src/sys/ufs/ufs/ufs_vnops.c:1157
2nd bufwait (bufwait) _at_ /usr/src/sys/ufs/ffs/ffs_vnops.c:263
3rd ufs (ufs) _at_ /usr/src/sys/kern/vfs_subr.c:2523

Perhaps this is a well-known LOR ? It happened when updating the src
tree with svnlite.

Full screenshot is available.

Regards,
René
