System is a HP Zbook 15, i9-9880H, 64GB RAM, 2TB SATA HDD with a T2000 Mobile GPU, Gentoo is installed. I keep seeing the following: Feb 21 14:49:13 cobalt kernel: nouveau 0000:01:00.0: fifo: fault 00 [VIRT_READ] at 0000000000019000 engine 0f [ce0] client 20 [HUB/HSCE0] reason 02 [PTE] on channel 7 [00ff998000 Renderer[20203]] Feb 21 14:49:13 cobalt kernel: nouveau 0000:01:00.0: fifo:000000:0007:[Renderer[20203]] rc scheduled Feb 21 14:49:13 cobalt kernel: nouveau 0000:01:00.0: fifo:000000: rc scheduled Feb 21 14:49:13 cobalt kernel: nouveau 0000:01:00.0: fifo:000000:0007:0007:[Renderer[20203]] errored - disabling channel Feb 21 14:49:13 cobalt kernel: nouveau 0000:01:00.0: Renderer[20150]: channel 7 killed! in the /var/log/syslog log every time Firefox crashes.I suspect some other software that uses the GPU exhibits the same. Wayland session, Gnome is v45. Libraries in use: Mesa 23.5.5 libdrm 2.4.120 xf86-video-nouveau 1.0.17 Kernel: 6.6.13, x86_64. All compiled from sources. Any ideas what else I can try to fix the issue with the GPU? I'm also happy to test patches or experiment with other things to resolve this issue. Many thanks, Alex -- Tactical Nuclear Kittens
