  Ok,  I've checked memory, and now I have booted system with crashlog

Here it is (please note, that panic() was called by ffs_valloc):

Previous frame inner to this frame (corrupt stack?)

  Full textdump:

  Please note, that FS was loaded by torrent client (40Mbit/s outbound
  traffic) and unpacking of svnmirror-base-r238500.tar.xz from this FS
  to itself. So, it was really high multistream load.

  I'll try to reproduce this on SINGLE disk, without geom_radi5 :)
