Title:
  nouveau core notifier timeout

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Newly installed Ubuntu 19.04 system. AMD Ryzen 3700X. NVIDIA GeForce
  RTX 2060.

  When the system is left for a while and the screen goes to sleep, then 
sometimes but not always, upon return there is no reaction to keyboard and 
mouse. Most likely the system is still running fine, but the only thing one can 
do is reboot. Afterwards, /var/log/kern.log shows lines like
  Sep 15 21:50:50 if kernel: [35590.756691] nouveau 0000:07:00.0: DRM: core 
notifier timeout
  Sep 15 21:50:52 if kernel: [35592.756660] nouveau 0000:07:00.0: DRM: wndw-0: 
timeout

  Ubuntu 5.0.0-27.28-generic 5.0.21

  $ sudo lspci -vnvn > lspci-vnvn.log
  pcilib: sysfs_read_vpd: read failed: Input/output error
