ad8: TIMEOUT - WRITE_DMA errors UFS 7.0-RC1

Same here. On an amd64 system with 1x sata disk (Western Digital Caviar
Green Power) on an amd690G chipset, with UFS and intensive disk activity
the system hangs and in the end it may panic. I've csupped today and
rebuild world & generic kernel but still it's very unstable, sometimes it
even hangs when activating geom volumes at boot time... 
I must add that this is a new system so I'm not 100% sure the hardware is sane.
Using ZFS it also crashed when doing intensive I/O.

I can supply additional info later if that may help.

Cheers,

Remco
