Hello Benjamin, Thank you for your response and for taking the time to look into the report.
I understand that, since the issue was reproduced on Linux Mint, it cannot be investigated further through the Ubuntu kernel bug tracker. I will report it to the Linux Mint team as suggested. For completeness, I also tested the newly released kernel 7.0.0-31-generic on the same machine, with the same NVIDIA 595.84 driver and the same configuration. The hibernation/resume problem is now completely fixed. My regression testing is therefore: - 7.0.0-28-generic: hibernation/resume works correctly - 7.0.0-30-generic: resume fails with nv_pmops_freeze [nvidia] returns -5 - 7.0.0-31-generic: hibernation/resume works correctly again, with the complete desktop session restored This strongly suggests that the regression introduced in 7.0.0-30 was fixed in 7.0.0-31. Thank you again for your assistance and for pointing me toward the appropriate channel for the Linux Mint-specific report.
