>Description:
While coping few big files (8x700MB) and 25GB of smaller files on GELI encrypted volume i got PANIC:

mode = 0121473, inum = 185008, FS = /mnt
Panic: ffs_valloc: dup alloc
UPTIME: 1h41m44s

Doing same operation on gbde volume or unencrypted file system works OK.

Backtrace:
mode = 0121473, inum = 185008, fs = /mnt
panic: ffs_valloc: dup alloc
Uptime: 1h41m44s

start coping files to encrypted volume. I've been coping about 30GB rdiff-backup (lots of small, gziped files) repository.

In about 2h You should get panic
