            Bug ID: 111044
           Summary: Resume up from suspend sometimes freezes system
                    (Optimus/Nouveau)
           Product: xorg

I'm on an Optimus laptop. Every time, I resume from suspend, I get this message
and the resume succeeds. 

tmp tpm0: tpm_try_transmit: send(): error -5

However, sometimes, I get this following messages and the system freezes:

nouveau 0000:01: 00.0: disp: outp 03:0006:0f81: link rate unsupported by sink
nouveau 0000:01: 00.0: disp: outp 03:0006:0f81: training failed

Not sure if this is relevant, but I also have a external multi-monitor setup.

$lspci -v | grep VGA
