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 System Information Manufacturer: SAMSUNG ELECTRONICS CO., LTD. Product Name: 90X3A Version: 0.1 Serial Number: CZPR93GB301834 UUID: 249F9300-1DD2-11B2-8000-89C120F0C461 Wake-up Type: APM Timer SKU Number: System SKUNumber Family: HuronRiver System
I can make this into a patch if necessary (drivers/acpi/sleep.c, right?). I am not /entirely/ sure it is the correct fix.
