Hi All,

I've got a highpoint raid controller that I'd been using with the ar 
(ata) driver for quite some time in -stable. Recently, before switching 
to DF, I'd been running with the highpoint raid driver - hpt374.ko ...

When I boot a DF kernel, I see -

Okay, what I see in -stable is -

Though the array is functioning perfectly.  So it isn't a DF thing...




Interestingly the highpoint bios utility thinks the array is just fine. 
 I'm going to try a reboot with my old -stable kernel just to see if it 
is indeed okay....

At any rate the 'usurping' messages are a bit weird ...

Cheers,

Andrew.
