I'm using GroovyArcade installed to a HDD - it's working like a dream but I have one issue. If I enable the Grub boot logo, I get a split screen image of the GroovyArcade logo, it animates for a while, a small purple box shows up with what appears to be a progress bar and then everything locks up (And the logo animation stops). If I disable the boot logo everything is fine, the screen quickly switches from the 30Hz split screen effect to a normal image. On shutdown the logo appears correctly.
Any ideas on how to address this? (Radeon X800 & generic 15Hz monitor)
