 Hi there,
 
 Sorry but FreeBSD 9.0-RELEASE still appears to have this issue.  When
 installed using BSD label partitioning scheme, a modification to
 ada0's label seems to nuke the kernel's view of the disk -- I can't
 think of a better way to explain it.  The disk itself is OK and the
 change makes it OK to the disk but the kernel can no more use the root
 partition until rebooted, returning weird errnos such as EIO or EXIO.
 No idea here if the bug is limited to BSD label scheme.
 
 Cheers,
 Yar
