Folks,

Something weird going on here.

I am using a Opteron 250 server with a Supermicro H8DA8, and LSI Logic
MegaRAID 320-1.

Using OpenBSD 3.8 everything works OK, but with a CURRENT the
header/sectors information does not seem to be accurate. Although the
total size is OK, looks like I am losing performance: running newfs is
noticeable slower on CURRENT. Can anyone confirm that?

I have already tried to use the correct information with fdisk/disklabel,
but that does not seem to make any difference.

Does anyone know whats going on? I am almost assuming this is a new issue
with ami.
