Dear Maintainer,
I updated the kernel on my Devuan Excalibur system and, after rebooting into the
new kernel, nouveau became unstable on my NVIDIA GK208B / GeForce GT 730.
System:
- Devuan GNU/Linux 6 (Excalibur)
- x86_64
- kernel affected: 6.12.73+deb13-1
- running kernel seen in logs: 6.12.74+deb13+1-amd64
- GPU: NVIDIA Corporation GK208B [GeForce GT 730] [10de:1287] (rev a1)
- Subsystem: Gigabyte Technology Co., Ltd Device [1458:3693]
- Kernel driver in use: nouveau
- Desktop/session: Xorg + XFCE/xfwm4 (via slim)
What led up to the problem:
- The system was previously working acceptably with nouveau.
- I updated the kernel.
- After rebooting into the newer kernel, graphical instability started.
Observed symptoms:
- screen pixelation / artifacts
- graphical session instability
- session logout / return to login
- repeated nouveau errors in dmesg
- errors seen both with Xorg and xfwm4
Expected result:
- normal graphical operation with nouveau, as before the kernel update
Actual result:
- graphical corruption and instability after booting the updated kernel
Relevant hardware info:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208B [GeForce GT
730] [10de:1287] (rev a1)
Subsystem: Gigabyte Technology Co., Ltd Device [1458:3693]
Kernel driver in use: nouveau
Kernel modules: nouveau
Relevant log excerpts:
[ 588.244769] nouveau 0000:01:00.0: gr: TRAP ch 4 [007fa3c000 xfwm4[2583]]
[ 588.244777] nouveau 0000:01:00.0: gr: GPC0/TPC0/MP trap: global 00000004
[MULTIPLE_WARP_ERRORS] warp 0009 [ILLEGAL_INSTR_ENCODING]
I also previously observed nouveau/Xorg-related failures ending with the X
session being killed and the login screen returning.
What I tried:
- I checked dmesg and found repeated nouveau GR/TRAP errors.
- I confirmed the GPU and active driver with lspci.
- I am disabling the XFCE compositor as a mitigation test.
Additional context:
- nvidia-detect reports that this card is only supported by the Tesla 470 driver
series, which is only available up to bookworm.
- Because of that, I am currently using nouveau.
Please let me know if you want:
- full unfiltered dmesg from boot to failure
- full Xorg log
- package list / kernel package details
- comparison with the previously working kernel

You need to report this to Devuan then.

Life would be so much easier if we could look at the source code.
