If I might add to this issue; I also have an XPS15, GTX 1650 and Ubuntu and POP!Os both trigger the issue (kernel 5.3.0-7625-generic). I also have deep as mem_sleep and use s2idle.
I have tried the following parameters without succcess: $ sudo kernelstub -a "rcutree.rcu_idle_gp_delay=1 acpi_osi=! acpi_osi='Linux'" $ sudo kernelstub -a "pcie_acpi=off" (In combination and alone) I have also tried forcing persistence with the driver which also did not work. Here is another thread in mint forums https://forums.linuxmint.com/viewtopic.php?p=1728952&sid=d2f654dfa1082400eeea98c9fbf01918#p1728952 The added parameters seems to work for them, but I could not resolve the issue. Nvidia driver is also at the latest version. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1847937 Title: 'gpu has fallen off the bus' after return from suspend Status in linux package in Ubuntu: Triaged Bug description: With this message the only way to resume work is to reboot the system using power button.
