SubjectRe: More breakage on HD7480D [ Aruba ]
Hi Ken,

*sigh* did I already mentioned that I hate PLLs? As soon as you fix
something another use case immediately starts to break.

Please provide dmesg output created with drm.debug=0xe with and without
the patch breaking it.

Thanks in advance,
Christian.
