Title:
System freeze with nvidia on-demand driver on kernel 5.11 and 5.13
Status in linux package in Ubuntu:
Confirmed
Bug description:
When using the on-demand mode on my GTX1060 Max-Q, the game CS:GO
causes a system hang after few minutes of playing (around 5min).
Nothing responds and the screen freezes, forcing a hard reboot. When
going back to the mode NVIDIA (performance mode), the game runs fine.
I am using gamemode to boost performances. It can also enable the GPU
while in the on-demand mode by setting the GAMEMODERUNEXEC environment
variable. To enable it, I added the following lines in my .profile:
if [ $(prime-select query) == "on-demand" ] ; then
export GAMEMODERUNEXEC="env __NV_PRIME_RENDER_OFFLOAD=1 env
__GLX_VENDOR_LIBRARY_NAME=nvidia env __VK_LAYER_NV_optimus=NVIDIA_only"
fi
Disabling gamemode doesn’t change anything, the system still freezes.
CS:GO is the only game doing this. I asked on the NVIDIA forums and
they told me it might be a kernel bug linked with async flip being
enabled in the Intel driver. In the attached nvidia log, you can see a
lot of the following errors when the freeze happens:
[ 327.526] (WW) modeset(0): flip queue failed: Invalid argument
[ 327.526] (WW) modeset(0): Page flip failed: Invalid argument
[ 327.526] (EE) modeset(0): present flip failed
The bug happens both on 470 and 495 drivers, and on kernel 5.11 and 5.13
(from linux-image-generic-hwe-20.04 and linux-image-generic-hwe-20.04-edge).
When going back to the 5.4 kernel (from linux-image-generic), the bug
disappears.
