I get a flood of kernel events from nouveau when connecting and disconnecting my 2nd display via the display port cable.
Events start with this:
nouveau E[ PDISP][0000:01:00.0] INVALID_VALUE [UNK84] chid 0 mthd 0x0700 data 0x00052002
modinfo nouveau -n
lspci -v | grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation G92GLM [Quadro FX 2800M] (rev a2) (prog-if 00 [VGA controller])
Errors come and go with connection/disconnection of the Display Port cable. So long as I stay running in init 3, the primary laptop LCD continues to function. Once I go init 5, X appears to start, and then just hangs.
I've attached dmesg output for boot-up, when I connect the display port, and when I disconnect the display port.
Please let me know if I can help in any way.
I should also add - I do not have this problem when running CentOS 7 - 3.10
Please attach your VBIOS as well (you can retrieve it from /sys/kernel/debug/dri/0/vbios.rom )
