After being annoyed that the latest Fedora 2.6.40 (aka 3.0 something)
kernels would not suspend/resume on my laptop I followed a Ubuntu forum
suggestion to use acpi=nonvs. This worked, or at least it is working
today with Fedora 15's 2.6.40.4-5.fc15.x86_64.
The system is also booting via UEFI if that makes any difference.
I understand that there is a no-NVS blacklist in the kernel. Should the
Samsung Series 9 be added to this list? Or could it be a different
suspend/resume problem entirely? I ask because resume used to work with
the 2.6.39 kernels, although it was flaky and would sometimes lock up.
This seems to be the necessary information for the blacklist, taken from dmidecode:
Handle 0x0001, DMI type 1, 27 bytes

I can make this into a patch if necessary (drivers/acpi/sleep.c,
right?). I am not /entirely/ sure it is the correct fix.

Please ignore this about nonvs. nonvs has nothing to do with the
suspend/resume problem on this laptop.
Instead it seems to involve reboots, which is crazy. From a cold
power-on start, suspend resume will always fail. But if the laptop is
rebooted first, suspend and resume appear to work. What the heck? I have
no clue how to debug this.
So now it appears that everything I ever tried to fix this only seemed
to work because I rebooted after changing GRUB or module options.

It is the Intel i915 driver. It is an Intel i5-2537M system with the
integrated video on the CPU.
lspci shows it as:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09) (prog-if 00
[VGA controller])

Well, that should work. I'm afraid I can't help you with this issue.

You might compare the output of intel_reg_dumper in the
working/not-working case before the i915 driver loads.

Could you provide any error logs you found? That could give us a clue as to
what is going wrong...

Sorry for the delayed response.
No, there were no error logs. I even tried the suspend debugging which
is supposed to write into the clock registers.
The symptom is that suspend appears to work correctly. Everything powers
down and the power light slowly flashes on and off. When the power
button is pressed to trigger resume, the fans come on, the power light
comes on full, but there is no hard drive activity and the screen does
nothing.
After forcing a power-off and rebooting, when using the "echo 1
> /sys/power/pm_trace" trick, the system has nothing in the dmesg about
resume failures. I have to wonder if it even started executing the
resume.
Other interesting info is that I have the laptop using UEFI and the
default reboot causes a kernel panic, so I have the kernel option
"reboot=k" set.
I just thought of this, could the EFI services be messing up the RTC
programming that pm_trace uses?
I suppose that I should also test suspend resume without UEFI, in BIOS
mode. Such a pain.
