I've created ata(4) software-raid with HPT370 ATA-RAID controller and two MAXTOR 6L040J2 (740X) 40GB hard drives. After that, problem appeared:

SALVAGE? [yn] y
I've removed ata-raid (ar0), mounted filesystems from first HDD (ad4), fsck, stressed, and everyting was OK (no such poblems). Then, I've mounted filesystems from second HDD (ad6), fsck, stressed, and everyting was OK, too. So, my hardware isn't faulty.
Then I've copied one drive to another (using dd or HPT BIOS), created ata-raid and after few hours my filesystems is in inconsistent state, again.
CPU cooling is OK and memory is well tested and reportd to be good.
This looks to be related with write operation on ar0, software ata-raid device.
>How-To-Repeat:
Create ata-raid on identical hard disks using dd+atacontrol or HPT BIOS. Run complete `make buildworld' 2-4x times. After hard working filesystem is corrupted and `make buildworld' fails.
>Fix:
Don't know.
