Subject: 3.12.9 kern.log spam from vgaswitcheroo

On Asus NP56D, if you use vgaswitcheroo to turn off the discrete GPU, the 
kernel starts spewing these messages endlessly, until /var/log partition fills up:

Jun  7 17:40:27 gamba kernel: [470008.702322] [drm:radeon_cs_parser_init] 
*ERROR* VM not ac
tive on asic!

Turning the discrete GPU back on stops the stream of messages.
