8.0RC1: panic: softdep_deallocate_dependencies: unrecovered I/O error
Hi.
I saw this panic just on?e during system shutdown, which
runs under VirtualBox. Sorry, I don't remember more details.
Unread portion of the kernel message buffer:
ad0: FAILURE - device detached
g_vfs_done():ad0s1e[WRITE(offset=7380582400, length=131072)]error = 6
/usr: got error 6 while accessing filesystem
