10/stable panic: softdep_deallocate_dependencies: dangling deps

[Dmitry Sivachenko]

Hello!

I have several machines with rather fresh FreeBSD-10/stable.

They all have 4 SATA drives, I have small gmirrored root+var and the rest of the drive space is mounted as /disk1, /disk2, etc (UFS2+SU).
When a single disk fails, system panics with "softdep_deallocate_dependencies: dangling deps" message:

Since all vital data (root+var) are mirrored, I expect OS to stay alive.
