With the 510.54 driver, hibernation works fine. When resuming, I get a flashing cursor for a bit, then the desktop appears.
With the 510.60.02 driver, resuming from hibernation fails. I get the flashing cursor as before, but then the monitors just turn off. At this point, I can ping the machine, but I cannot login via SSH. Trying to switch to a console with Ctrl-Alt-F1/2/etc doesn’t do anything. After rebooting I don’t see anything in the logs after the start of the hibernation.
I’ve attached pre- and post-hibernate reports with the 510.54 driver, and a pre-hibernate report with the 510.60.02 driver. Obviously I can’t get a post-hibernate report with 510.60.02…
I’ve performed some of the tests suggested here Debugging hibernation and suspend — The Linux Kernel documentation
- All the hibernation test modes (/sys/power/pm_test) work.
- Writing test_resume to /sys/power/disk does not work.
