Hpt Rocketraid 454

[Rhiannon]

Hello
Sorry my bad english

I use RocketRaid 454.
Mainboard: MSI kt4av-l
CPU: AMD XP 2000+
RAM: 2x512MB DDR333
HDD: Samsung SV0411N (40.0 GB)-RAID1 

I install FreeBSD 4.9-RELEASE with hpt374-4.9 (374-r5-bsd-v121.zip -
http://www.highpoint-tech.com) to RAID1 via HPT Rocketraid 454.

#: bonnie -d /usr -s 2048
or
#: cd /usr/src
#: make buildworld

/kernel: dev =#da /0x20006, block = xxxxx, fs=usr
/kernel: panic: ffs_blkfree: freeing free block
/kernel:
/kernel: syncing disk ... 12 5 5 5 ...

and restart.

Why? What is this error?
