I finally had another bad reboot and remembered to run the ACPI debugging steps. However a diff on the output of `sudo dmidecode` showed no differences from the one in a good session, and the only difference in the /proc/acpi files was that in battery/BAT0/info, my battery's design voltage was listed as 123340 mV instead of 123600 mv (but I don't think this is related because I'm in a good session again and my battery info says 123340 mV this time too).
I did a suspend and restart though, and like before when the GPU wasn't active, the computer powers up, but the screen never comes on. I've copied the kernel log from that session to include. First, I have updated the kernel so I'll include the new `uname -a`. ** Attachment added: "Output of `uname -a` for bad session" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1009312/+attachment/3343277/+files/uname -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009312 Title: GPU loads unreliably, possible kernel timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1009312/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
