After an update last week, something is bloating up the messages and warn files in my /var/log/ folder. Closer inspection revealed that the following line was printed to the files every 0.000001 seconds resulting in 3 files of 20GB filling up completely my disk space:

nouveau 0000:01:00.0: fifo: PBDMAO: 81206000 [ILLEGAL_MTHD] ch 2 [003fc71000 X[1722]] subc 0 mthd 0000 data ffffffff

I am not an experienced user and have no idea how to fix this.

I am using openSUSE Tumbleweed (version ID: 20191101) on a Lenovo T430 laptop.

It looks like a known bug on nouveau driver (if i remember well, this is the opensource driver for NVidia graphic cards).

Source: https://bugs.freedesktop.org/show_bug.cgi?id=99900

To fix this you can:

  • Use logrotate or a cron job to flush logs passed a given size.

or

  • Tweak your syslog configuration to avoid logging this.

or

  • Totally disable syslog (rarely usefull on a desktop system).

or

  • Stop using nouveau driver (install proprietary one or use vesa).

  • Could you possibly provide a step-by-step for a permanent solution, please? Commented Jan 9, 2023 at 15:43
  • Not sure what it's called on openSuse but look for a proprietary Nvidia driver. Which one exactly also depends on your display card; the beginning of your Xorg.log or similar should identify the model. Commented Jan 9, 2023 at 16:45

This is not a permanent solution, but to boot-up past the error messages:

  • On
  • F2
  • Boot Manager
  • F2 + Shift

  • The system boots, your answer ist not the answer to his question. Commented Jan 13, 2023 at 8:04
  • Not quite; I was getting the exact same errors. This is how you can Boot in Insecure Mode, so as to then download and install drivers. A useful step nonetheless. Commented Jan 13, 2023 at 9:58
