JMicron Raid Problems on a Gigabyte GA-P35-DS3

[Phil Higgins]

There's also another related issue with the handling of this controller's metadata - if you're not running raid 0, the device name isn't null terminated.

Added null termination and stripping out the spaces made it work for me.

I can post a fairly simple patch for it if people want it and rc15 is not coming really soon. (Have to clean it up a little to make it presentable)

Andreas,

a patch to solve this issue will be in 1.0.0.rc15.
