Description

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.
