On an older PC which worked perfectly so far, with i5 760 & 8GB RAM, and NVIDIA Corporation GT216 [GeForce 210] (rev a2) graphic card, Kubuntu 16.04 with standard kernel Linux quox 4.4.0-116-generic, recommended Nvidia driver 340.106-0ubuntu0+gpu1 I’m occasionally (eg no user activity in GUI or login screen, PM screensaver activated, suspend to RAM, resume from RAM, logout & reboot etc) getting blank screen after recent drivers and kernel upgrade.
There is “NVIDIA(GPU-0): Failed to initialize DMA.” in Xorg log.
The OS/Kernel is OK, I can login via ssh over network.
The following line is repeates 1000s of times in kern.log:
kernel: [ 9813.926021] NVRM: Xid (PCI:0000:01:00): 6, PE007e
plus few similar ones, eg
kernel: [ 1231.828871] NVRM: Xid (PCI:0000:01:00): 6, PE0005
This renders the PC box hardly usable.
Any idea what could be wrong?
