Hi,
I'm running 11.0-CURRENT r287391 with KERNCONF=A20,
the hard disk is connected on the SATA port.
It seems it can not read/write the disk reliably.
# newfs -U /dev/ada0
/dev/ada0: 476940.0MB (976773168 sectors) block size 32768, fragment size 4096
using 762 cylinder groups of 626.09MB, 20035 blks, 80256 inodes.
