Change the default for the vfs.bdev_buffered sysctl to zero.
This means that access to block devices nodes will act the
same as char device nodes for disk-like devices.
If you encounter problems after this, where programs accessing
disks directly fail to operate, please use the following command
to revert to previous behaviour:
sysctl -w vfs.bdev_buffered=1
And verify that this was indeed the cause of your trouble.
See the mail-archives of the arch@FreeBSD.org list for background.
