Nouveau DRM failure on 5120x1440 screen with 5.8/5.9 kernel
...have a laptop with a VGA card (specs below) connected to a 5120x1440
screen. At boot time, the card correctly detects the screen, tries to allocate
fbdev fb0, then the video hangs completely for 15-30 seconds until it goes
blank.
This used to work in Linux 5.7 and earlier, although it allocated a 3840x1080
fb instead of a 5120x1440. I've attached the full dmesg. I tried commands like
video=DP-2:3840x1080 but it doesn't help.
Linux 5.8 boots without hanging if the laptop is not connected to the 5120x1440
screen.
PCI specs:
01:00.0 0300: 10de:0dfc (rev a1)
01:00.0 VGA compatible controller:...
