Today when starting the box with i386 RELENG_5 I got the following:

ad4: TIMEOUT - WRITE_DMA LBA=4798015
ad4: TIMEOUT - WRITE_DMA LBA=146847331

panic: initiate_write_inodeblock_ufs2: already started

After a reboot & fsck it works nice!

A verbose dmesg (from a good boot) is here:

I really don't know what to with this box, maybe put regular ATA or SCSI 
disks in it?
