Created attachment 198021 [details] dmesg after resume when started with nomodeset and after pm_test core [1.] One line summary of the problem: [HP Compaq dc7800 Small Form Factor PC] suspend/resume failure [2.] Full description of the problem/report: Suspend to RAM fails, the PC will not wake up again. It only works if I suspend to disk before, then I can suspend to RAM afterwards (as many time as needed) until the PC is rebooted again.

The PC has the latest BIOS v1.35 (November 27, 2015, http://ftp.hp.com/pub/softpaq/sp73501-74000/sp73582.exe). I originally reported this bug to Ubuntu (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1375995). With the latest Ubuntu version 15.10, suspend never works, the workaround with first suspending to disk no longer works. With Arch Linux on the same PC, suspend to RAM works after suspending to disk. Testing with pm_trace fails resuming, echo none > /sys/power/pm_test echo 0 > /sys/power/pm_async echo 1 > /sys/power/pm_trace echo mem > /sys/power/state dmesg reports [ 0.295437] Magic number: 0:788:178 [ 0.295439] hash matches drivers/base/power/main.c:1065 [ 0.295475] acpi device:0e: hash matches [ 0.295499] platform: hash matches When I start the kernel with parameter nomodeset and then suspend to RAM, after resuming the screen stays dark, but the machine reacts to keyboard input (I can type reboot or hit Ctrl-Alt-Del). It will also execute a script which is started after the suspend command, e.g. dmesg. A dmesg output after such a resuming with nomodeset is attached to this message. When the kernel is started normally (i.e. with modeset), the machine seems dead, it does not execute scripts or react to keyboard input and I have to power it off forcefully. I also tested removing all modules, but it does not change the situation. Removing the i915 requires nomodeset, and this case works the same as nomodeset without removing modules, i.e. the machine reacts, but the screen is dark. All tests with pm_test succeed, e.g. echo core > /sys/power/pm_test echo mem > /sys/power/state The dmesg output after this test is also attached. Things I tested without success: acpi=off acpi=linux noapic
It's a very long comment and I will summarize it as: the PC doesn't resume unless nomodeset added to kernel cmdline, in which case, the screen isn't turned on after resume but reacts to keyboard and able to reboot with ctrl-alt-del. I would say this is a GPU driver issue, move it there.
