Could be the VBIOS problem which upstream is adressing on their website: http://nouveau.freedesktop.org/wiki/TroubleShooting/#index10h3
Adding the follwoing kernel boot parameter solved the problem on my laptop with kernels 3.13 or higher: nouveau.config=NvBios=PRAMIN The error message I got when booting without this parameter was: nouveau E[ VBIOS][0000:05:00.0] 0xc581[ ]: unknown opcode 0x00 nouveau E[ DEVINIT][0000:05:00.0] init failed, -22 nouveau E[ DRM] failed to create 0x80000080, -22 Regards, Markus Huber -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
