Wake from sleep freezes with 460 driver

My system freezes up when woken from sleep. This behaviour happens with the 460 drivers and not with the 450 drivers. I have a laptop with an intel i7 and nvidia M1000M and have tested both with prime offloading enabled and disabled. When waking the screen remains black for around 1/2 minutes after which I can see the login screen, but it is entirely frozen and a forced restart is required.

Here are my nvidia bug reports with the two different drivers, and the system log around the time that it crashed on wakeup.

Display engine push buffer channel allocation failed: 0x65

Seems to be a common bug with the 460 drivers, like

Thanks, indeed that issue seems related, especially the behaviour observed by chris.bainbridge. I it is possible to mark my report as duplicate? Marking the question as answered doesn’t sound right, after all it is still unclear how to fix it.
