>Description:
I got error with VIA 694 ATA controller. Errors (from dmesg) is  UDMA ICRC ERROR. Machine works normaly only with PIO 4 mode enabled. Attached device is  Seagate Barracuda ata V drive. Drive & motherboard is tested with differ os'es (linux,  win nt 5.0 win nt 5.1) and works normaly. Decreaceing ata mode to 4 , 2 , or 1 is not helps with this trouble. I cannot see any big corruptions on drive but system reboots with some unwritten buffers.
>How-To-Repeat:
Install FreeBSD to VIA 694 / 694T chip based motherboard. It's repeats both on 5.2 and 4.9
