Even with a dump, it could be hard to determine.  Without it, fairly
unlikely to prove conclusively.

Make sure that your filesystems are clean with a thorough fsck on
boot.  Also try to rule out hardware problems; specifically memory
and the disk itself.

You didn't mention the version of FreeBSD you're running (normally a
"uname -a" is useful in a tech support message), but updating it might
help.  The iir driver has not had any major improvements in a year or
so, but those changes look important.
