Subject: Samsung Series 9 seems to require acpi=nonvs to resume properly
Date: Thu, 29 Sep 2011 14:51:46 -0600 [thread overview]
Message-ID: <1317329529.3151.10.camel@knife> (raw)

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.
