Hi,

today I saw this error in messages:

: fsync: giving up on dirty
: 0xc5564110: tag devfs, type VCHR
: usecount 1, writecount 0, refcount 78 mountedhere 0xc54ef800
: flags ()
: v_object 0xc556645c ref 0 pages 1146
: lock type devfs: EXCL (count 1) by thread 0xc5236a50 (pid 39)
: dev mirror/gm0s2e.journal
: GEOM_JOURNAL: Cannot suspend file system /vol0 (error=35).

Is it something harmful, or is it "normal" behavior? It was in time when 
generating backup (high disk I/O).
Gjournal is on top of gmirrored SATA disks.

mirror/gm0s2d is 2GB journal provider
mirror/gm0s2e.journal is 380GB data provider
