reboot while writing to USB device

[Erich Dollansky]

Hi,

i just got a reboot while a backup was done to an USB device. I found
later hundreds of messages like this in /var/log/messages

May 19 10:24:32 X220 kernel: softdep_deallocate_dependencies: got error

I ran a fsck on all partitions of the affected device. No errors were
found. The source file file has had a small problem. The e-mail I was
writing was properly stored but firefox lost the data of the currently
opened tabs.

Uname says:

FreeBSD X220.alogt.com 10.0-STABLE FreeBSD 10.0-STABLE #28: Sat Apr 19

amd64

The source and the destination file system are cyphered with geli.

What does this error 6 mean?
