Since I switched from MBR partitioning and Grub to GPT partitioning and Grub2 my system fails to resume from time to time. dmesg output (only "PM:" lines): $ journalctl --dmesg | grep PM: Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0x000a0000-0x000fffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0x0253e000-0x0253efff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0x0254d000-0x0254dfff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0x0255e000-0x0255efff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0x0256d000-0x0256dfff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbc4f000-0xcbc93fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbc94000-0xcbd08fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbd0b000-0xcbe10fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe12000-0xcbe12fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe13000-0xcbe1afff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe1b000-0xcbe1bfff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe1c000-0xcbe1dfff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe1e000-0xcbe25fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe26000-0xcbe46fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcbe47000-0xcbe89fff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcc000000-0xcf7fffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xcf800000-0xdfffffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xe0000000-0xe3ffffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xe4000000-0xfed1bfff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xfed1c000-0xfed1ffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xfed20000-0xfeffffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registered nosave memory: [mem 0xff000000-0xffffffff] Jan 07 18:38:57 linux-3yod kernel: PM: Registering ACPI NVS region [mem 0xcbc4f000-0xcbc93fff] (282624 bytes) Jan 07 18:38:57 linux-3yod kernel: PM: Registering ACPI NVS region [mem 0xcbe12000-0xcbe12fff] (4096 bytes) Jan 07 18:38:57 linux-3yod kernel: PM: Registering ACPI NVS region [mem 0xcbe1b000-0xcbe1bfff] (4096 bytes) Jan 07 18:38:57 linux-3yod kernel: PM: Registering ACPI NVS region [mem 0xcbe1e000-0xcbe25fff] (32768 bytes) Jan 07 18:38:57 linux-3yod kernel: PM: Registering ACPI NVS region [mem 0xcbe47000-0xcbe89fff] (274432 bytes) Jan 07 18:38:57 linux-3yod kernel: PM: Checking hibernation image partition /dev/disk/by-uuid/7c287338-bb71-41e1-a5cf-789f6fea25d3 Jan 07 18:38:57 linux-3yod kernel: PM: Hibernation image not present or could not be loaded.

My system: * openSUSE 13.2 * Kernel 3.12.5 (Kernels >= 3.13 do not suspend; this problem is probably causes by "radeon" driver for my ATI Radeon HD 3450 graphics card) * Intel DH55TC mainboard After looking in the kernel sources (kernel/power/snapshot.c) I found, that there is some issue with "nosave pages". Is there something I can do? Greetings, Björn -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
