Hello community and nvidia-devs,

I recently upgraded from 1030gtx to Quadro P4000 and started experiencing 2 efects:

  1. Complete freeze of desktop, only hard reset help.
  2. KDE Plasma subsytem restart - no windows are recovered

I am on Gentoo Linux architecture: x86_64
Nvidia drivers: 470.63.01
Kernel: 5.13.10-gentoo-x86_64 (Gentoo patches, not Vanilla)
No issues with temperature

But I noticed here on forum that one of your devs reported back in 2020 GL in user namespace - #16 by scott.c.arnold its going to be fixed as soon as broken driver expected /dev/nivida-modeset to be nobody:nobody while its on most distros root:root, but I on Gentoo have these:
[17:47:47] zangetsu@andromeda  $  ~  ls -la /dev/nvidia-modeset
crw-rw---- 1 root video 195, 254 Oct 3 11:02 /dev/nvidia-modeset

Can you please repoort a bug and eventually fix this? Its happening about 7x per day…

Thank you.

Ladislav

Ok, I am now testing following kernel parameter:
rcutree.rcu_idle_gp_delay=1
processor.max_cstate=1

compiling at moment…

Here is my full kernel boot parameter config:
GRUB_CMDLINE_LINUX=“iommu=pt intel_iommu=on pcie_acs_override=downstream,multifunction nvidia-drm.modeset=1 rcutree.rcu_idle_gp_delay=1 processor.max_cstate=1”

I will also next test add: pcie_aspm=off, but have seen it reported as not helping.
