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):

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 :)
