Comment # 14 on bug 1205774 from Bruno Friedmann

With kernel 6.0.12 + nvidia 525.60.11 still same issue.

I'm now able to reproduce 100% of time the crash, which lead me to believe it
has something to do with DisplayPort Multi-Stream Transport.

The architecture here is Laptop docked to Dell E-Plus dock, main DP goes to
Dell 27" 4k P2715Q monitor.
The second DP port on the monitor is linked to the second external.

There's no issue if the monitor is used alone. If you activate MST Primary on
this monitor to allow chaining to second, and you poweroff the second monitor
the crash occur.

I've seen that this driver has been touched since August
